2 Recent LST Science results

The Large-Sized Telescopes (LSTs) are an important part of the forthcoming Cherenkov Telescope Array Observatory (CTAO), the future cornerstone of very high-energy gamma-ray astronomy. The first LST, LST-1, was inaugurated in late 2018 on La Palma, Canary Islands, began regular gamma-ray observations in November 2019 and has so far collected more than 2000 hours of observations. The LST-1 sensitivity was assessed with 48 hours of Crab Nebula observations, which show that the performance closely matches the expectation obtained with Monte Carlo simulations.

In this talk, we will highlight key scientific achievements by LST-1 over recent years. These include the detection of several flares of active galactic nuclei, like the detection of flaring activities of the blazar BL Lac, which prompted the first Astronomical Telegrams from the CTAO era, the radio galaxy NGC 1275, and notably, the first high-energy detection of the distant flat spectrum radio quasar OP 313 (z=0.997). The current research program also includes studies of pulsars and their nebula, in particular the Geminga pulsar, as well as studies of extended Galactic sources and the pursuit of gamma-ray emissions from gamma-ray bursts. These observations not only deepen our understanding of cosmic phenomena but also serve as crucial tools for fundamental physics research, including the search for axion-like particles, dark matter, and tests for violations of Lorentz invariance.

Finally, we will share the progress on the construction of additional LSTs as well as further prospects for the core science project of the LST collaboration, including but not limited to additional AGN observations and follow-up programs of various transient phenomena.

3 A probabilistic expanding universe under functors of actions

In this contributed talk, I will discuss how to embrace information by presenting important concepts of abstract information field theory, probabilities, and probabilistic dimensions, in the view of functors of actions theories and other abstract theories. I will present a collection of manifolds and metric systems with probabilistic notions, different flavors of an expanding sub-manifold to metric systems describing simpler dynamics of space around massive objects. Furthermore, I will talk about the derivation of the equation of motions of a simplified gravity model in a probabilistic expanding Universe. Finally, I will introduce the notions of probabilistic actions and concepts of novel categories of abstract field-particles, such as the probablons and informatons. These are the first steps towards a concrete description of a probabilistic gravity, and a probabilistic expanding Universe.

4 Leptons from HF (Heavy-Flavor) decays : Measurements and Inferences towards small systems

The early universe was in a high temperature and high density environment for a very brief period after the Big Bang.In order to recreate this state of matter in the laboratory, mini bangs are created by colliding heavy ions at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory and subsequently at the Large Hadron Collider (LHC) at CERN. In this talk I shall be covering on the selected results from LHC and RHIC. I shall be covering spectra and correlations (flow) and also nuclear modification factor. I shall be discussing quarkonia flow. Due to the larger mass of the bottomonium states compared to the charmonium ones,the measurement of bottomonia production in proton-nucleus collisions allows a study of CNM effects in a different kinematic regime, therefore complementing the J/Psi studies[1]. For smaller systems like p+A and p+p we have less deeply bound bottomonia states and thus a comparatively larger chance to escape. This means that more states become measurable, which is a positive feature. On the other hand, it also means that the escape mechanism which underlies the anisotropic flow of bottomonia may become largely ineffective, in particular for the Upsilon(1S).
Accordingly,the measurement of a sizable flow for Upsilon(1S) in small systems[2] would probably hint at the importance of initial-state correlations. Our present understanding of sQGP as a very good liquid with astonishingly low viscosity will be discussed including the recent observations of QGP-like phenomena in small collision systems[3].The understanding small systems hence becomes very important and such studies will be also stressed and discussed[4].

5 Equation of state of quark gluon plasma in dynamical magnetic fields

We investigate equation of state (EoS) of quark gluon plasma (QGP) in the presence of dynamical magnetic fields. Since it is believe that the intense magnetic field generates at BNL and CERN, we study not only the static magnetic field but also dynamic magnetic fields in order to analyse the impact of these field on EoS. We found significant altering on EoS in the presence of a magnetized field in QGP. Results are enhanced appreciably in the presence of dynamical magnetic field as compared to static magnetic field. Results are useful in the presence of dynamical magnetic fields in order to explore various feature of QGP at RHIC and BNL.

6 Rate of the Small-strip Thin Gap Chambers (sTGC’s) in the New Small Wheels of ATLAS

The instantaneous luminosity of the Large Hadron Collider at CERN will be increased by about a factor of five with respect to the design value by undergoing an extensive upgrade program over the coming decade. The largest phase-1 upgrade project for the ATLAS Muon System was the replacement of the first station in the forward regions with the New Small Wheels (NSWs) which took place during the long LHC shutdown in 2019-2021. The two Small Wheels cover a positive and negative pseudorapidity acceptance in the range $| \eta |$ = 1.3 to 2.7. Both Small Wheels have been successfully installed in ATLAS in 2021 and took data from p+p collisions at 13.6 TeV in 2022, 2023 and 2024. Along with resistive strips Micromegas, the NSW's are equipped with eight layers of small-strip thin gap chambers (sTGC). The new system is designed to assure high tracking efficiency, reduction of fake trigger rates and precision measurement of muon tracks. In this presentation we will show results on the rates of the sTGC detectors.

7 Detector and physics simulation using heavy ion collisions at NICA-SPD

The space-time picture of hadron formation in high-energy collisions with nuclear targets is still poorly known. The tests of hadron formation was suggested for the first stage of SPD running. They will require measuring charged pion and proton spectra with the precision better than $10\%$. A research has been carried out to check feasibility of such studies at SPD. In this work, $^{12}C-{^{12}C}$ and $^{40}Ca-{^{40}Ca}$ heavy ion collisions at center of mass energy of 11 GeV/nucleon were simulated using the SMASH event generator. Firstly, the generator-level events were studied. The distribution of track multiplicities and momentum distributions of different types of charged particles were obtained. Secondly, the generated events passed through the full reconstruction using the SpdRoot framework. At this stage particles were identified using $dE/dx$ measurement and time-of-flight information. It allowed us to estimate charge track multiplicities in the tracking system and purities of charge particles spectra. The results on multiplicity are important to estimate occupancies in the tracking system, while the results on the pion and proton momentum spectra show that particle identification should be acceptable for validation of hadron formation models. This is the first study of moderate ion collisions for the SPD Collaboration.

Keywords: Hadron formation effects, Heavy ion collision, SMASH, NICA-SPD, Rapidity, Charged track multiplicity, Particle physics event generator.

8 Thermodynamic free energy calculation under one loop correction at finite chemical potential

We calculate thermodynamic free energy under one loop correction at
finite chemical potential. Due to the effect of the chemical potential in
this one loop correction, the formation of bubble droplet is obtained with
the value of quark and gluon parametrization in the range of
q = 1/8 and
8
q ?
g ? 18
q. However the stability of the droplet is able to obtain
in the range of some parametrization of quark and gluon as
q = 1/8 and
12
q ?
g ? 16
q. It implies that the fluid dynamics of the quark, anti-
quark and gluon exist with the stable and unstable droplets depending
on the different quark and gluon parameter values. It means that such
phenomenological parameters can induce in the droplet formation of QGP
and it may stabilize the droplet depending on their values. However the
size of the stable droplet after the incorporation of chemical potential is
bigger than the size of droplet without the chemical potential at this one
loop correction factor.

9 Study of first-order event plane correlated directed and triangular flow in heavy-ion collisions at high baryon density region by STAR

Anisotropic flow parameters $(v_{n})$ are important observables as they provide insight into the collective expansion and transport properties of the medium produced in relativistic heavy-ion collisions. Among these parameters, directed flow ($v_1$) describes the collective sideward motion of produced particles in heavy-ion collisions. It is an important probe to study the in-medium dynamics as it is predicted to be sensitive to the equation of state (EoS) of the produced medium. Minimum in the slope of directed flow ($dv_1/dy$) as a function of collision energy has been proposed as a signature of the first-order phase transition between hadronic matter and Quark-Gluon Plasma (QGP). Triangular flow $(v_3)$ typically arises from the initial state fluctuations and is expected to be uncorrelated with the reaction plane. However, recent measurements at lower collision energies (higher baryon chemical potential ($\mu_{B}$)) of $\sqrt{s_{NN}}$ = 2.4 and 3 GeV, show a correlation between $v_3$ and the first-order event plane angle ($\Psi_{1}$).

In this presentation, we will report the measurements of $\Psi_{1}$ correlated $v_1$ and $v_3$ for $\pi$, K, $p$, net-kaon, net-proton, $d$, $t$, and ${}^{3}He$ in Au+Au collisions at $\sqrt{s_{NN}}$ = 3.2, 3.5, 3.9, and 4.5 GeV taken in fixed-target mode from the second phase of the beam energy scan (BES-II) program at RHIC-STAR. We will show the dependencies of $v_1$ and $v_3$ on rapidity, centrality, and collision energy, and subsequently, discuss their physics implications. The experimental measurements will be compared with the results from the JAM transport model to understand the underlying physics mechanisms at low collision energies.

10 An Intriguing examination of Band Head and Spin Levels in Superdeformed Nuclei in 130 mass region

Our analysis focuses on the Superdeformed (SD) bands in the A~130 mass region using a modified Variable Moment of Inertia (VMI) model for a comprehensive examination of band-head spin and level spins. Due to the lack of experimental data for these bands, our model primarily aims to deduce the band-head spin. By utilizing this model, we can obtain quantitative results for γ-energies and spins across all observed bands. We can also examine other significant properties using VMI model. To ensure the accuracy of the band-head and level spins, we verified the predicted spin with Ratio of Transition Energies over Spin (RTEOS). Notably, we found a strong agreement between the calculated and observed transition energies and spins, indicating the reliability and precision of our approach. A key outcome of our study is the calculation of band-head spins and level spins within the Superdeformed bands of the A~130 mass region. These findings are instrumental in resolving the tentative nature of level spins and identical bands, offering valuable insights for future research in this field.

11 Ferrite Superconductivity

This proposal describes the arrangement based on the Einstein de-Haas experiment. An externally applied magnetic field magnetized the ferrite core by giving microwave power frequency to the coil around the ferrite core. Ferromagnetic resonance is achieved due to the effect of the interaction of spin precession magnetic moments due to Zeeman splitting on the macroscopic magnetization of the material. The core attains negative permeability at ferromagnetic resonance. Due to negative permeability, the ferrite counteracts the magnetisation due to the applied DC electric field given to one end of the ferrite core. In certain scenarios, negative permeability can lead to the expulsion of the magnetic field resulting in B equal to zero inside the material. This induced phenomenon is somewhat analogous to the Meissner effect observed in superconductors. In the case of negative permeability, the negative magnetic response effectively shields the material's interior from external magnetic fields. The curl of the magnetic field is zero resulting in a net force equal to zero on the moving charge carriers.

12 A relativistic explanation to the darkness of galactic halos

We extend previous results of a relativized Newtonian dynamics derived for the case of inertial rectilinear motion, to the case of a uniformly rotating disk. The results uncover a nonluminous component coexisting with the luminous component in a dynamical duality governed solely by rotation velocity. We apply the obtained results to infer the dynamics of luminous and nonluminous matter in a diverse sample of 52 galaxies from the Spitzer Photometry & Accurate Rotation Curves (SPARC) data set. For each galaxy, we calculated the radial density distributions of the luminous and nonluminous matter components based solely on its measured rotation curve. For all the tested galaxies, the predicted radial density profiles of the nonluminous components are faithful traces of the measured rotation curves. The nonluminous component is predicted to dominate over the luminous component starting from a radial velocity of V_flat/3. For rotation velocities v→ V_flat, the luminous component vanishes almost completely and the bulk of the matter becomes nonluminous. All the tested galaxies are expected to be strongly dominated by their nonluminous component (0.846 ≤ f_NLM ≤ 0.990, σ_(f_NLM )= 0.034). Moreover, in agreement with the Radial Acceleration Relation (RAR), the correlation between the estimated total masses of the luminous and nonluminous components, and between the luminous component and the total dynamical mass are very strong (r= 0.947, and 0.954, respectively). In addition, consistent with the Baryonic Tully-Fisher Relation (BTFR), the correlation between the total luminous mass and V_flat is quite high (r = 0.626).
These results demonstrate that key features attributed to the existence of exotic dark matter particles in galactic halos, are accounted for by simple relativistic considerations.

Keywords: Dark matter, nonluminous matter, dark matter in galaxies, matter-dark matter coupling, rotation curve, SPARC, Radial Acceleration Relation, Baryonic Tully-Fisher Relation.

13 Tethered probes unveiling black hole

Black holes, enigmatic cosmic entities with immense gravitational pull, remain among the most intriguing objects in astrophysics. Traditional strategies of studying them face severe obstacles in their extreme environments. This paper proposes a pioneering approach to enhance astronomical exploration of black holes using tethered probes equipped with modular sensor suites and robust backup structures.
These advanced probes promise continuous data transmission, power supply, and retrieval capabilities, overcoming the challenges posed through the intense gravitational fields and radiation near black holes. Modular sensor suites onboard the probes are designed to capture a comprehensive range of data, which includes gravitational waves, electromagnetic emissions, and particle compositions. This multifaceted data collection will significantly broaden our understanding of black hole dynamics and their interactions with surrounding matter.
Critical to the success of these missions are the integrated backup systems, which ensure mission resilience against potential malfunctions in the hostile surroundings. These systems include redundant communication channels, power sources, and mechanical components, ensuring uninterrupted data collection and operational reliability.
By harnessing these technological advancements, this novel strategy holds the potential to revolutionize our information of black holes, offering exceptional insights into their formation, evolution, and fundamental properties. This approach not only expands our knowledge of astrophysical phenomena however additionally paves the way for future breakthroughs in gravitational physics and cosmology.

14 Particle production mechanism in O + O collisions at √ sNN = 200 GeV using EPOS4

The study of QGP formation in RHIC experiments provides insight into the
strong force that binds quarks and gluons, also enriching our knowledge about the conditions of the early universe. Several measurements from both small and large collision systems, examining the same observables such as strangeness enhancement across different energies, suggest QGP-like behavior in all these systems. Recently, STAR experiment at RHIC collected a large data sample in oxygen-oxygen (O + O) collisions at √ sNN = 200 GeV. Oxygen is the lightest nucleus compared to the Au, Cu and P b and expected to overlap the multiplicity coverage between small and large systems at RHIC. In this study, we have used recently developed version of the EPOS (EPOS4) to study the production of identified particles (π±, K± and p(p)) in O + O collisions at √sNN = 200 GeV. Predictions of transverse momentum (pT) spectra, ⟨pT⟩,integrated yield (dN/dy) for different centrality classes are studied. To provide insight into the collective nature of the produced particles, we look into the pT-differential particle ratios K/π and p/π. It is observed that the EPOS4 successfully produce the typical shape of the charge particle multiplicity (dN/dη) and mean transverse momentum (⟨pT⟩). Additionally, EPOS4 in O + O collisons at √sNN = 200 GeV also predict the final multiplicity overlap among pp, Cu − Cu, dAu and Au − Au collisions.

17 Expansion of QGP droplet in the early universe

We study the expansion of a quark-gluon plasma (QGP) droplet in the early universe using a phenomenological model. This model employs the Friedmann approach to compute the equation of state for the QGP. Studying the behavior of the QGP droplet at non-zero chemical potentials during the early universe is challenging. Our analysis explores temperature and other thermodynamic observables, incorporating fitting parameters to account for the chemical potential's impact. This inclusion is crucial, as it significantly influences the variation of thermodynamic variables over time. This study provides valuable insights into the expansion of QGP droplet during the early stages of the universe, particularly in the presence of chemical potential.

19 Diphotons existence with the effect of finite chemical potential

We employ a phenomenological model to scrutinize the diphoton signal, a highly regarded and widely explored probe that serves as one of the premier indirect signatures of quark-gluon plasma (QGP) in relativistic heavy-ion collisions. Theoretical considerations indicate the potential existence of a finite chemical potential at RHIC, LHC, and in astrophysical environments. The existence of finite chemical potential was also confirmed by experimentalists. Diphotons, being particularly sensitive in high-temperature and chemical potential regions, play a crucial role in these scenarios. Our calculations of the diphoton mass spectrum, utilizing the quasiparticle approach with a consideration for chemical potential, reveal notable enhancements compared to scenarios with zero chemical potential. The results elucidate the significance of diphotons, especially in terms of the augmented mass spectra attributed to the presence of chemical potential. Ultimately, our model aligns well to corroborate the detection of QGP and provides insights into the properties of diphotons arising from relativistic heavy-ion collisions.

21 Investigation of sources affecting longitudinal particle production in heavy-ion collisions using spectators

Understanding the sources controlling the longitudinal distribution of produced particles in relativistic heavy-ion collisions is crucial for characterizing the shape of the Quark-Gluon Plasma (QGP). Previous measurements on forward-backward multiplicity correlations, directed flow, and flow decorrelations have provided strong model-dependent constraints on emission profiles of initial state sources. Therefore, understanding the longitudinal evolution of particle production is essential for constraining various models of heavy-ion collisions.

In this talk, we will present correlation coefficient $\rho(nA_{sp}, nA_{ch,\eta})$, as a function of pseudorapidity ($\eta$), between the forward-backward asymmetry of initial-state spectators ($A_{sp}$) and final-state multiplicities ($A_{ch,\eta}$) in Au+Au collisions at $\sqrt{s_{NN}}$ = 200 GeV using a multi-phase transport model (AMPT) to quantify the contribution of preferential emission from initial state sources to the longitudinal distribution of produced particles. Additionally, the sensitivity of the correlator to spectator matter dynamics, such as fragmentation and evaporation, will be discussed. These findings motivate the experimental measurement of this correlator to constrain initial state sources that control the longitudinal particle production of the QGP matter.
