7 Concept of the Spin Physics Detector

The study of the spin effects and polarization phenomena at NICA at high luminosity (up to 10$^{32}$ cm$^{-2}$ s$^{-1}$) a of longitudinally and transversely polarized proton and ,especially, deuteron beam collision requires the development of Spin Physics Detector (SPD) placed at the second interaction point of the collider. SPD consists of the superconducting magnetic system, inner silicon tracker, straw tube tracker, particle identification system, electromagnetic calorimeter and muon range system. The free-streaming DAQ system will allow to store about 4 MHz events. The progress in the development of different SPD subsystems is presented.

Speaker: Dr Vladimir Ladygin (VBLHEP JINR)

8 Physics program of the SPD experiment at NICA.

The SPD experiment at the NICA collider aims to investigate the nucleon spin structure and polarization phenomena in collisions of longitudinally and transversely polarized protons and deuterons at $\sqrt{s}$ up to 27 GeV and luminosity up to 10$^{32}$ cm$^{-2}$ s$^{-1}$. Production of the Drell-Yan pairs, charmonia, prompt photons and high-p$_T$ hadrons will be the main instrument to access the full set of the leading order transverse momentum-dependent PDFs of nucleons. Physics program of the experiment will be presented in details.

9 Is orbital angular momentum efficiently transferred to spin degreeds of freedom at NICA energies?

We compute the relaxation time for quark/antiquark spin and thermal vorticity alignment in a quark-gluon plasma at finite temperature and quark chemical potential. We model the interaction of quark/antiquark spin with thermal vorticity as driven by a phenomenological modification of the elementary quark interaction with gluons. We find that in a scenario where the angular velocity produced in a peripheral heavy-ion collision competes with transverse expansion, and thus is small, quarks/antiquarks take a long time to align their spin with the vorticity. However, when the angular velocity created in the reaction is large, the alignment is efficient and well within the lifetime of the system created in the reaction. The relaxation time is larger for antiquarks which points out to a difference for the polarization of hadrons and antihadrons when this alignment is preserved during hadronization.

11 Finding resonances, unitarity, peculiarities and traps

Finding resonances in amplitudes parametrized by us is an old well-known but controversial issue. Despite the apparent simplicity, it can cause many serious problems and surprises. By performing an analysis of the amplitudes fitted to the data, it's easy to find pecularities and come across traps. They are especially important when planning a precise definition of resonance parameters. The purpose of the presentation is to show what may be the effects of neglecting such problems and how to avoid them. The key here is unitarity and crossing symmetry.

12 String fusion effects at NICA energies

The multiparticle production in the relativistic collisions of hadrons and nucli is often considered in a two-stage approach. At the first stage, a certain number of quark-gluon strings is produced, and the final particles are produced by strings decay. The formation and fragmentation of strings is implemented in various Monte Carlo generators, such as PYTHIA, HIJING, FRITIOF, AMPT, UrQMD, etc. However, a number of new and precise measurements from the SPS, RHIC and LHC experiments shows that the many observed effects don't fit into the picture of the individual, non-interacting strings.
Among the observables sensitive to the collective effects are the multiplicity dependence of the transverse momentum, forward-backward correlations and strongly intensive measures, charge and particle ratio correlations and fluctuations, strangeness and charm production.
In this work, we studied the effect of the interaction between strings in pp and AA collisions using at NICA energy range. We applied a dipole-based Monte Carlo model [1, 2], in which the interaction between strings is implemented according to string fusion model [3, 4]. The model takes into account also the finiteness rapidity length of strings, allowing at NICA energies to probe different ranges of baryon density. For the particle species discrimination, the modified Schwinger mechanism is used [5], where the effective string tension, according to the string fusion prescription, depends on the string density. The results demonstrate that the inclusion of string fusion improves the agreement of the model predictions with experimental data. We discuss the possibilities of new measurments using MPD detecter at NICA.

The reported study was funded by the Russian Foundation for Basic Research according to the research project 18-32-01055_mol_a.

13 QCD phase diagram at NICA - K+/pi+ horn effect and light clusters in THESEUS Topic: Heavy-Ion Collisions and QCD Phase Diagram at NICA

I report on recent progress in the development of the Three-fluid Hydrodynamics-based Event Simulator Extended by UrQMD final State interactions (THESEUS) [1] as a tool for investigating signals for the onset of deconfinement and the formation of a hadron-quark matter mixed phase in heavy-ion collisions at NICA energies. I shall cover three main topics:
1. The study of the MPD detector acceptance influence of the baryon stopping signal for deconfinement in the net proton rapidity distributions for the NICAS beam-energy scan [2].
2. Extension of the particlization routine to include light cluster production (deuterium, tritium) and application to study thermal and coalescence schemes; comparison with results from NA49 at 20 and 30 AGeV as well as preliminary results from HADES at 1.3 AGeV with preliminary conclusions on the role of in-medium effects [3].
3. Development of the thermal model scheme of particlization to study the K+/pi+ and K-/pi- ratios as a function of the beam energy, based on the Beth-Uhlenbeck approach to Mott dissociation of kaons and pions in hot, dense quark matter at the hadronization transition [4].

14 Pixel detectors for the Inner Tracking System of NICA MPD

One of the key problems of modern relativistic nuclear physics is the study of the phase diagram of strongly interacting matter. These experiments try to answer the question of how the transition of the QGP to the hadron gas occurs. To resolve such ambitious problems of studying hot and dense baryonic matter occurring in the relativistic heavy ion collisions, a new mega set-up is currently being developed at JINR: Multi-Purpose Detector (MPD) at NICA collider [1]. The main element of this MPD set-up it will be tracking system, required for the precise determination of track vertices with subsequent track reconstructions of all detected charged particles in a wide range of transverse momentum and pseudo rapidity.
The monolithic active pixel sensors based on CMOS technology are also being considered as building block for the construction of the vertex and inner tracker of the NICA MPD. These sensors were developed for the upgraded Inner Tracing System of ALICE experiment in CERN [2].
In this overview the properties and characteristics of multicomponent detector modules as basic elements for the precise determination of primary and secondary vertices together with new ultralight, radiation-transparent carbon fiber support structures (all detector modules are mounted on these structures) will be reported. Also possible use of these technologies for the experiments SPD, BM@N and NA61/SHINE will be discussed.
The reported study was funded by RFBR according to the research project № 18-02-40075.

20 Short-lived resonances and neutral mesons in the physical program of the NICA-MPD

Short-lived hadronic resonances such as $K*(892)^{0,\pm}$, $\rho(770)^{0}$, $\phi(1020)$, $\Sigma(1385)^{\pm}$, $\Lambda(1520)$ and $\Xi(1530)^{0}$) are used to study different aspects of particle production and collision dynamics in pp, p—A and relativistic heavy-ion collisions. The yields of resonances are sensitive to the competing processes of hadron rescattering and regeneration, thus making these particles unique probes of the properties of the late hadronic phase. Measurements of resonances with different masses and quantum numbers also provide insight into strangeness production and processes that determine the shapes of particle momentum spectra.
We discuss results of the model-based studies of the influence of the
hadronic phase on the measured properties of resonances in heavy-ion
collisions at NICA energies. Moreover, we discuss prospects for resonance measurements in the MPD experimental setup and results of the feasibility studies obtained using Monte Carlo simulation of the detector performance.

21 Current status of the Time-of-Flight system of the MPD

Mass production of detectors and modules of the MPD TOF system was launched in March 2019. Currently, the production process of all elements of the Time-of-Flight system has stabilized but is passing slightly behind schedule. The report will present the reasons behind this lag, and an updated schedule will be presented taking into account the current situation.
In addition, the report will present the latest simulation results of the Time-of-Flight system with the newest detailed geometry in the MPDROOT and the status of creating service subsystems.

22 Mini Beam-Beam monitoring: a wake-up trigger detector for the TOF of MPD

Progresses on the design of an inner mini Beam-Beam (MBB) monitoring de- tector to help triggering the TOF is described. This consists of a cylinder 60 cm in length and 52 cm in diameter with strips located on the surface of the cylinder along its axis consisting in arrays of 2cm x 2cm x 0.3 cm$^{3}$ scintillating plastics separated by 1cm. This detector is proposed to be part of MPD and is being developed by the MexNICA group. We also show the first mechanical and structural design for mBB together with the corresponding strength and mechanical simulation results using the CAD software. Also, using MC simulations, we show the performance of the scin- tillating plastic squares coupled each to four SensL Silicon Photomultipliers (SiPM) sensors. These studies show the importance of sensor location on the plastic sensitive area. Finally, we describe the advances in the front-end design based on fast signals from the used SiPMs. Triggering instrumentation design for Time of Flight (TOF) detector awake is also presented along with TRB3 interfacing for fast signal processing, independent from trigger circuitry.

23 Development of the Fast Interaction Trigger for MPD experiment

The fast triggering of nucleus – nucleus collisions and the precise TOF measurement with picosecond time resolution are important features of all experiments at RHIC and LHC colliders.

The Fast Interaction Trigger (FIT) system is an important part of the Multi-Purpose Detector (MPD) setup for study of Au + Au collisions with beams of NICA collider in the energy interval 4 ≤ sqrt(Snn) ≤ 11 GeV. The main aims of the FIT are (1) fast and effective triggering of Au + Au collisions in the center of the MPD setup and (2) generation of the start pulse for the TOF detector.

The fast vertex-trigger signal, provided by Fast Forward Detector (FFD), is the main signal of the L0 trigger of MPD. The fast determination of z-position of collision point of the vertex requires the appearance of pulses with high amplitudes in both sub-detectors FFDe (East side) and FFDw (West side) and it defines the trigger efficiency. For this aim the pulses of each sub-detector are fed to sub-detector electronics unit. Two-threshold method is used to get a good time resolution, only LVDS pulses with lengths above a threshold value (corresponding to photodetector output pulses with large amplitudes) are used for production of sub-detector pulses Te and Tw. The time of generation of these pulses is defined by appearance of the first good pulse from sub-detector modules.

This presentation will cover the main design concepts, detector construction, beam test results, and the results of detector performance studies.

24 Correlation femtoscopy at NICA energies

The correlation femtoscopy gives possibilities to measure the space-time characteristics of particle production processes due to the effects of quantum statistics (QS) and final state interactions (FSI). Femtoscopy at lower energies was intensively studied at AGS, SPS and in the Beam Energy Scan (BES) program.
Results on pion and kaon correlation femtoscopy for the NICA energy range are shown in the work. Also, a set of auxiliary tools to perform simulation with the vHLLE+UrQMD model in a simpler manner is presented. A new package to be used for femtoscopy analysis is announced and first correlations functions got directly from the model are shown.

26 Particle production properties at SPS energy range - recent results from NA61/SHINE experiment.

The research programme of the NA61 collaboration covers a wide range of hadronic physics in the CERN SPS energy range. It encompasses measurements of hadron-hadron, hadron-nucleus as well as nucleus-nucleus collisions. The latter are analyzed to better understand the properties of hot and dense nuclear matter. In this contribution recent results on particle production in proton-proton, Be+Be, Ar+Sc interactions at beam energies of 19/20A, 30/31A, 40A, 75/80A and 150/158A GeV/c will be presented as well synergies with future NICA program will be emphasised.

27 Fluctuations and correlations study at NA61/SHINE

The strong interactions program of NA61/SHINE, a fixed-target experiment at the CERN SPS, focuses on the search for the critical point of strongly interacting matter. The strategy of the Collaboration is to perform a comprehensive two dimensional scan of the phase diagram $\mu_{B} – T$ by changing the collision energy and the system size. If in this scenario, the system freeze-out occurs in the vicinity of the possible critical point, then a region of enhanced fluctuations is expected in suitable fluctuation measures. 

The talk will review the ongoing NA61/SHINE analysis on multiplicity and transverse momentum fluctuations in terms of intensive and strongly intensive quantities. Furthermore, their pseudorapidity dependence, which corresponds to a scan in the baryon chemical potential $\mu_{B}$ at the freeze-out stage, will be presented along with the study of the higher moments of multiplicity distributions.

The talk also discusses the approaches to corrections of the results and possible systematic problems in the analysis.

29 NA61/SHINE detector upgrade

The NA61/SHINE detector, at the CERN SPS, is undergoing a major upgrade during the LHC Long Shutdown 2 period (2019-2021). The upgrade is essential to fulfil the requirements of new open charm measurement program. It is necessary to stress that this new physics goal can be achieve only when the readout rate will be increase by a factor 10 and the resolution of the secondary vertex in the high multiplicity tracks environment of Pb-Pb events will be improved. The following elements of the experiment are parts of the upgrade: Time Projection Chambers (TPC), Vertex Detector (VD), Beam Position Detectors (BPD), Particle Spectator Detector (PSD) and Time of Flight detectors (TOF). On top of the detectors, new Trigger and Data Acquisition (TDAQ) system is being developed. In the proposed talk the progress on design and development of new detectors and TDAQ system for NA61/SHINE experiment will be presented.

30 ALICE technologies proposed for the VD of NA61/SHINE in connection to the future MPD Si tracker

In this report I would like to show, first of all, briefly, the main challenges of the Inner Tracking System (ITS) design for ALICE that were successfully met, which is proved by 10 years of operation at the LHC. Secondly, the conceptual current design of the Vertex Detector for open charm at the NA61/SHINE will be discussed for two options of Small and Large Area Detector systems (SAVD and LAVD). Status of SAVD and LAVD are to be presented. This includes both the implementation of record breaking carbon fiber technologies and MIMOSA sensors performance of SAVD and the expected future ALPIDE applications for LAVD. And, finally, some ideas on possible synergies with the future ITS for MPD are also discussed.

31 Upgrade of the NA61/SHINE ToF system based on a MRPCs for the NICA experiments

The obsolete left-right time-of-flight system (TOF-LR) of the hadron spectrometer NA61/SHINE require upgrades due to significant ageing of scintillators, photo-multipliers, power supplies as well as the outdated readout electronics and cables. New TOF detectors based on multi-gap resistive plate chambers (MRPC) for the NICA experiments are proposed as a replacement.
The progress on design and development of new TOF system for NA61/SHINE experiment will be presented in the report.

32 Synergy in the development of forward hadron calorimeters for NA61, BM@N, MPD and CBM experiments

The lead/scintillator transverse and longitudinal segmented forward hadron calorimeters will be used in the upgraded NA61 and BM@N experiments and future CBM, MPD experiments to measure centrality and reaction plane orientation in heavy ion collisions. Similar calorimeter has been already used at the NA61 experiments on the search for the critical point and the onset of deconfiment in nucleus-nucleus interactions.
The light detection in all of these calorimeters is provided by the micropixel photodiodes and signal readout is provided by sampling ADCs. At present, already constructed modules for the future CBM experiments at FAIR are used at the NA61 upgraded hadron calorimeter and at the new hadron calorimeter in the BM@N experiments.
Mutual interest in the the forward hadron calorimeters developments for these experiments, including development of different approaches of the centrality determination, calibration procedure will be discussed.

34 Convolutional neural network for centrality determination in fixed target experiments

Fixed target experiments have an unique possibility to measure centrality of colliding systems by hadronic calorimeters on the beam line. This is usually achieved by the detection of all forward nucleon spectators and accomplishes fluctuation and correlation measures with lower biases than in collider experiments. However, hadronic calorimeters have much lower resolution than multiplicity detectors that introduces additional volume fluctuation to the measures.
In this work, we present the first attempt to increase the resolution capacity of the spectator detector by implementing a convolutional neural network to the modular structure of the Projectile Spectator Calorimeter of the NA61/SHINE experiment. The data were generated in the framework of SHIELD Monte-Carlo event generator with detector response simulated with GEANT4 for the collisions of the lightest available system (${}^7$Be+${}^9$Be) and for the highest beam momentum (150A GeV/c). Two ways of determination centrality -- by a number of forward spectators and by forward energy -- are considered. In comparison with the classical centrality selection method, the neural net shows a significant increase of centrality selection accuracy after implementation.

35 A “vector finder” approach to track reconstruction in the Inner Tracking System of MPD/NICA.

At present, the accelerator complex NICA [1] is being built at JINR (Dubna). It is intended for performing experiments to study interactions of relativistic nuclei and polarized particles (protons and deuterons). One of the experimental facilities MPD (MultiPurpose Detector) [2] was designed to investigate nucleus-nucleus, proton-nucleus and proton-proton interactions.

As one of the possible MPD upgrade steps, an Inner Tracking System (ITS) based on the next generation silicon pixel detectors [3] is being considered to be installed between the beam pipe and the Time Projection Chamber (TPC). It is expected that such a detector will increase the research potential of the experiment for both the proton-proton (high luminosity) and nucleus-nucleus (high particle multiplicity) interactions. According to the proposed design, the MPD ITS will consist of five layers of silicon pixel detectors. The main purpose of the ITS is to provide a better precision of the primary and secondary vertex reconstruction and improve track reconstruction in the MPD in the region close to the interaction point.

The existing in the MPD track reconstruction method is based on the Kalman filter in the TPC. Its simple extension to the ITS is not adequate to fully exploit the potential of the new detector, therefore such a method cannot be considered as a good tool to study ITS performance. That is why another algorithm, based on the “vector finder” approach, was developed. The talk will describe the proposed track finding algorithm for the ITS of MPD and present its performance results obtained on Monte-Carlo generated data of nucleus-nucleus collisions.

36 Performance studies of anisotropic flow with MPD at NICA

The Multi-Purpose Detector (MPD) at NICA collider has a substantial discovery potential concerning
the exploration of the QCD phase diagram in the region of high net-baryon densities and moderate temperatures.
The anisotropic transverse flow is one of the key observables to study the properties of dense
matter created in heavy-ion collisions. The MPD performance for anisotropic flow measurements is
studied with Monte-Carlo simulations of gold ions at NICA energies $\sqrt {{S_{NN}}} = 4 - 11 GeV
using different heavy-ion event generators. Different combinations of the MPD detector subsystems
are used to investigate the possible systematic biases in flow measurements, and to study effects
of detector azimuthal non-uniformity. The resulting performance of the MPD for flow measurements is
demonstrated for the directed and elliptic flow of identified charged hadrons as a function
of rapidity and transverse momentum in different centrality classes.

37 Study of energy distributions in FHCal

We propose to study the angular distributions of the energy deposited in FHCal modules. The obtained distributions were fitted by the linear function on event-by-event basis. This fit allows to extract the transverse gradient of the spectator energy in the calorimeter and also the energy carried by free spectators inside the beam hole. The clear correlations between the fit parameters are observed in full range of the collision centralities.
Assuming, that the peripheral area of FHCal is occupied mainly by the produced particles (pions), it can be possible to subtract their energy contributions to the full FHCal energy. It makes possible to calculate the energy of free spectators in the central collisions and to avoid the ambiguity in FHCal energy depositions for central and peripheral events. Potentially, the developed approaches would help in the determination of the centrality of the collision with FHCal without application of the TPC information on multiplicity.

38 Centrality Determination in Heavy-ion Collisions with MPD (NICA)

Centrality is a key parameter for defining the collision system size in relativistic heavy-ion collisions.
It provides a tool for selecting events according to cross section in a similar way in different
experiments and with theoretical model calculations.
The progress of centrality determination in Au+Au collisions at
Multi-Purpose Detector (MPD) at the future NICA collider is presented.
The choice of variables used for event classification will be discussed.

39 MPD electromagnetic calorimeter simulation

In a frame of the NICA / MPD project, a unique cylindrical electromagnetic calorimeter (ECal) is being created. Recently, the design of the power frame made of carbon fiber was completed. This led to significant changes of the calorimeter structure. This report gives a brief description of the new ECal geometry, the modification of simulation procedure and the current basic parameters of the calorimeter. The ECal geometry simulation is based on the standard software of
the MPD detector: MpdRoot and FairSoft. In the new version, the calorimeter consists of 38,400 “shashlik” towers with 210 layers combined from a 1.5 mm scintillator plate and 0.3 mm lead plate coated with reflective paint. The shapes of the towers are approximately a truncated pyramid with a base of 44 cm2 and of 64 types, more accurately described by a set of trapezoids. All towers look at the point of the beam intersection, forming the so-called projective geometry. Each calorimeter module is formed of 16 towers. All modules are placed in 50 baskets with a total weight equal to 1.2 tons each. As part of this program, independent module options have been developed to use in the test measurements on cosmic ray and electron beams. This work was supported by RFBR grants № 18-02-40054 and № 18-02-40079.

41 Extraction of multiple parton interactions from forward-backward multiplicity correlations

Forward-backward multiplicity correlations have been studied in electron-positron, proton-proton and more recently in lead-lead collisions. For the proton-proton case, comparison of experimental results to different models reveals an incomplete understanding of the physical phenomenon associated with these correlations. In this work, we present a study of forward-backward multiplicity correlations in proton-proton collisions using the PYTHIA event generator, at LHC energies. A detailed analysis is presented with and without weak decays, splitting data samples into soft and hard QCD processes, and comparing the computed correlations for short and long range pseudorapidity regions. Each of these regions is analyzed accounting for the effects of color reconnection and independent multiple parton interactions. We show that a combination of these effects is required to explain the latest measurements on proton-proton data. Furthermore, is shown that from measurements of multiplicity correlations is possible to extract the average number of multiple parton interactions in the event producing these correlations, and albeit model depending, to predict the strength of these correlations, not yet measured, for higher energy collisions

42 Beauty = Truth. On the role of aestheics in physics

Modern theories of physics are elaborate, math-heavy constructions that aim to encompass the workings of the world in the largest possible scales on the one hand (relativistic cosmology), and on the deepest subatomic level on the other (quantum field theories). What they share in common is the special kind of raw, majestic beauty, which not only enthralls theorists (including Einstein and Dirac), but sometimes even drives their scientific pursuits. But what actually makes a theory "beautiful"? In order to answer this question, during this popular lecture we shall take a quick walk starting from the very dawn of (mathematical) physics all the way to the current search for grand unification. Can aesthetics really lead us closer to the truth, or is beauty a luring, but deceiptful guide that should have no place in the logical and empirical method of physics?

44 Electromagnetic Calorimeter of the MPD at NICA

ECal type "shashlik" having sampling 300 micron Pb and transverse cell size ~4x4 cm2 has the ability to measure energy with the resolution up to 5% in the range of energy at NICA.
Due to not fully projective geometry of the detector (the reason is the large scatter of the interaction point), in certain cases, a correction of the hit position depending on the interaction point is needed. As an example, it is shown that using this correction when restoring π0 can reduce the sigma in two times.
It found an easy method to calibrate calorimeter using cosmic muons.

45 Main parameters of MPD Electromagnetic Calorimeter in Latest Geometry Version.

As part of the NICA/MPD project, a unique cylindrical electromagnetic calorimeter (ECal) is being created with a diameter of 2 m, a length of 6 m and a total weight of about 60 tons. Recently, the design of a 12-ton power frame of ECal made of carbon and glass-plastic was completed. This led to the need for a significant changes in the structure of ECal. A new program for the geometric description of ECal was created, including both the power frame and the new structure of the modules and their layout. The report is devoted to the first presentation of the main characteristics of ECal. The power frame contributes 10.9% of the radiation length in front of the ECal (in addition to 17.2% of the TOF), and also adds plastic partitions from 0.2 to 14 mm thick between the modules. This leads to an average decrease in the total ionization signal from the ECal by 10%, which weakly affects the energy resolution, which remains at 4.5% for 1.0 GeV photons, but significantly distorts the Gaussian shape of the energy response distribution due to an increase in the low-energy tail. The energy and angular accuracy of the ECal and their dependence on the photon energy and the threshold of the electronics, the detection efficiency of photons, muons and neutrons, the expected resolution in the mass of the neutral pion will be given. This work was supported by RFBR grant No. 18-02-40054.

48 A MAPS based Inner Tracking System of the Multi-Purpose Detector at the NICA collider

The Multi-Purpose Detector (MPD) is being constructed to study the properties of extremely dense nuclear matter formed in relativistic nucleus-nucleus collisions at NICA energies. The yields of strange and charmed particles are the important observables sensitive to critical phenomena in phase transitions of the QGP-matter at high net-baryon density. Highly efficient registration of such short-lived products of nuclear interactions using vertex silicon detectors will play a key role in the analysis of the possible onset of deconfinement in nuclear matter.
An Inner Tracking System (ITS) based on the Monolithic Active Pixel Sensors (MAPS) is under design by the emerging MPD ITS collaboration in Dubna and Wuhan. The ultra-light carbon fiber structure carries five layers of CMOS ALPIDE sensors recently elaborated by the ALICE collaboration. The two layers of the Outer Barrel (OB) are built out of 42 staves developed for the new ALICE ITS to be installed at CERN next year. The MPD ITS mainframe mechanics and the OB installation is planned to be completed in 2023. The Inner Barrel (IB) will use novel MAPS sensors of enlarged area and reduced thickness to be developed together with the ALICE collaboration within 2020-2025 and installed after the reduction of the diameter of the MPD beam pipe to optimal value of 38 mm will become possible.
The report presents the main details of the MPD ITS layout, computer simulations of the pointing resolution gained with the system, as well as a quality assessment of the MPD tracking system including ITS and Time Projection Chamber used for the reconstruction of the multi-strange hyperons and the D-mesons produced in the central Au-Au collisions at = 9 GeV.

49 Status of the proposal for a beam-beam monitoring system for the MPD

The MexNICA collaboration proposed in 2016 a beam-beam monitoring detector system (BE-BE) for the MPD-NICA experiment. This BE-BE detector is able to provide complementary capabilities such as a trigger signal for MPD to identify and to discriminate beam-beam minimum bias or centrality events from background and beam-gas interactions. Additionally, the BE-BE detector is useful for luminosity measurements and event plane resolution studies. In this talk we present the status of the BE-BE design, the status of prototype tests and recent simulations to highlight its capabilities, relevant for the stage 2 of MPD experiment.

53 Software developments for detectors experimental hardware

Big modern physics detector experiments represent a collaboration of workgroups and require wide variety of electronic equipment. All devices can be classified into two categories - Data Acquisition (DAQ) equipment and hardware that is not time-critical and can be run at low priority.
But the statuses and stored data from these systems, such as high voltage systems, gas systems, temperature sensors, front-end electronics, etc. play notable part in the experiment operation and further data analysis.
Monitoring, control and archiving of the values from the devices must be centralised and unified to simplify data access and interaction between detectors and subsystems.

59 Naming and Numbering Convention for the Equipment Database of the NICA project.

In every big scientific project human influence creates disorder. For an investment as big as NICA it is crucial to organize all the elements and minimize the chaos. One of the ways to achieve this goal is to create an Equipment Database (EqDb). Each component in the EqDb will receive its individual Part Identifier. Naming and Numbering Convention is a document containing instructions for Part Identifier creation. It was based on the existing model from CERN [1]. These Part Identifiers will simplify component identification at the location.

60 HIC simulations with different EoS models

We have developed and performed a Bayesian analysis for selecting the most probable equation of state under a set of constraints from compact star physics, which now include the tidal deformability from GW170817. The calculations for two-parameter family of hybrid equations of state, which produces a third family of hybrid stars in the mass-radius diagram, have been made. We are preparing to apply our Bayesian analysis method also for extension of hybrid equations of state for the symmetric matter case for the finite temperatures, which will be used for HIC simulations. The results of simulations for Rapidity Distribution and Curvature at Midrapidity as well as hadron Ratios at Midrapidity will be used in Bayesian analysis method to obtain the probabilities for the model parameters within their considered range.

61 The dosimetry protection of the MPD Electronic Equipment at the new NICA Collider – the prototype system

“The prototype dosimetry system to protect NICA Slow Control electronic equipment” project was started in Dubna at the beginning of 2018. Its primary purpose is to design a prototype dosimetry system for continuous monitoring of Multi-Purpose Detector (MPD) Slow Control electronic equipment which can protect it against accidental ionizing radiation caused by the NICA collider failure or its abnormal functioning. The system will be fitted out with alarming features which can inform chosen people about crossing the safe threshold of the radiation and the electronics will be possibly destroyed by the irradiation. Then the controlled switching off of the Nuclotron-based Ion Collider fAcility (NICA) Complex can be possible. The system can also be utilized for protecting the personnel working on electronic platform near the MPD against the radiation. The presentation describes the prototype system status of hardware and software after almost two years of work. There will be also presented the plans for the future.

62 Beam-Beam Collisions Monitor for NICA

The Fast Beam-Beam Collisions (FBBC) monitor, based on the application of the secondary emission detectors – the Micro Channel Plates (MCPs), is proposed for NICA experiments at JINR. Two interaction points are foreseen for beam intersections at NICA: one for heavy-ion studies with the Multi-Purpose Detector (MPD) and another one for the polarized beams for the Spin Physics (SPD) experiment. The fast MCPs with the improved performance characteristics such as low resistivity (100-500 MOhm) 6μ channels, high efficiency of MIPs registration and high gain (~107), the extended life duration, very short signals with fast rise-time (~0.8ns), are proposed for the event-by-event monitoring of the beam-beam interactions. The ultra-high vacuum compatibility and the low-mass compact design allow the application of the MCP setup inside the vacuum beam-pipe.
The conceptual design of the Beam-Beam Collisions detector and fast readout electronics is presented and discussed.

67 Average high energy neutron flux distribution in the Quinta sub-critical assembly irradiated with proton beam of 0.66 GeV energy applying the actinide spectral index method

The paper presents the results of investigations of nuclear-physical characteristics of neutron fields generated in a massive uranium target irradiated by deuterons with an energy of 0.66 GeV. 23 natural uranium samples spatially arranged in a sub-critical assembly Quinta (at the Joint Institute for Nuclear Research, Dubna , Russia), were irradiated with spallation neutrons. We have processed the experimental data based on gamma-ray spectrometry in order to reach (obtain) the number of neutron induced fissions and neutron captures in the detector foils. Applying the try and error method we have found that the neutron energy for which the ratio of the fission cross section to the capture cross section of the natural uranium from the nuclear data base is equal to the measured ratio of the spectral indexes. The retrieved distinct fission and capture cross sections for the distinct neutron energy from the nuclear data base describe the average values which enabled us to evaluate the average neutron flux and neutron fluency distribution in the assembly.

68 Probing the QCD critical end point through multi-messenger observations of compact stars and heavy ion collisions.

In order to prove the existence of a critical end point (CEP) in the QCD phase diagram it is sufficient to demonstrate
that at zero temperature $T=0$ a first order phase transition exists as a function of the baryochemical potential $\mu$,
since it is established knowledge from ab-initio lattice QCD simulations that at $\mu=0$ the transition on the
temperature axis is a crossover.

We present the argument that the observation of a gap in the mass-radius relationship for compact stars which proves the
existence of a so-called third family (aka "mass twins") will imply that the $T=0$ equation of state of compact star
matter exhibits a strong first order transition with a latent heat that satisfies $\Delta\epsilon/\epsilon_c > 0.6$.
Since such a strong first order transition under compact star conditions will remain first order when going to symmetric
matter, the observation of a disconnected third family branch of compact stars in the mass-radius diagram proves the
existence of a CEP in QCD.

To quantify the mass twins phenomenon, I will show a recent developed EoS that features of a color superconducting
chiral quark model with nonlocal, covariant interactions bearing density dependent vector meson coupling and a
density-dependent bag pressure. This model allows for a scenario where the compact stars of the GW170817 event are
either both hadronic, both hybrid, or simultaneously hadronic and hybrid configurations, expected to be identified
through the detection of gravitational radiation produced by compact star mergers.

In order to study the information derived from compact star observations, I shall review the method of estimation of
tidal deformabilities of compact stars (encoded in gravitational radiation of mergers) and present results for pure
hadronic as well as hybrid stars that include the mass twins case. In particular, the recent detection of gravitational
radiation from the GW170817 event shed light on the properties of the neutron star equation of state (EoS), thus
comprising both the study of the symmetry energy, stellar radius and the mass twins scenario. Along these lines, at the
end of my talk I shall present an analysis of star rotations aimed at probing the compact star maximum mass which turns
out to strongly constrain the maximum density found in star cores.

91 α, β, γ radiation monitoring in the working area of the MPD Slow Control electronic equipment.

Project focuses on α, β, γ radiation monitoring. Firstly, three Gamma-Scout detectors were tested if the measurements taken in the same location are equal within 5% uncertainty. Next, detectors where moved to three different locations. Data collected from those locations in three available working modes (detection of γ, β+γ and α+β+γ radiation) was analyzed to determine potential influence of the rack’s case on radiation levels. Also, based on received data of radioactive sources (Eu-152 and Thorium) tested using Radateh photoelectronic detector three spectrograms were generated and compared, to conclude best utility of each type of detector. Further tasks involved developing software for a self-built Geiger-Müller counter using NI myDAQ and LabVIEW environment.

103 Setup of the heat transfer inside the TOF-MPD detector

Time of Flight (TOF) detector is a part of Multi Purpose Detector (MPD), crucial element of the NICA complex. The detector generates signal that carries information needed for the particle identification. Complex physical proces of forming output signal requires maintaining the amplifier circuits at specific temperature. Overheating may induce major signal distorsions and - in worst case – damage of the detector. To avoid that scenario, many thermal simulations were performed.
The aim of this work was to build instrument for multipoint temperature measurement inside the TOF module and collect the essential data to verify the simulations. To assemble this setup, Pt100 type RTD sensors and LUMEL SM1 modules were used. Next, in order to multiply input channels, custom multiplexer circuit were built. Afterward, specialised LabVIEW software was created for circuit control and data aquisition.
