The understanding of the production of (hyper) clusters at midrapidity is presently one of the largest theoretical challenges in the physics of relativistic heavy ion collisions. We study this production employing the Parton-Hadron-Quantum-Molecular-Dynamics (PHQMD) approach [1], a microscopic n-body transport model based on the QMD propagation of the baryonic degrees of freedom with density...
The creation of loosely bound objects in heavy ion collisions, e.g.~light clusters, near the phase transition temperature ($T_{\rm ch} \approx 155 MeV$) has been a puzzling observation that seems to be at odds with Big Bang nucleosynthesis suggesting that deuterons and other clusters are formed only below a temperature $T\approx 0.1-1 MeV$. We solve this puzzle by showing that the light...
Light nuclei production is a hot research topic in heavy-ion collision at RHIC-BES. The observed non-monotonic behavior with the colliding energies[1,2] was declared to be related to the critical point of the QCD phase diagram[3,4]. In this talk, we focus on investigating the light nuclei production with and without critical fluctuations within the framework of the coalescence model.
In the...
The existence and the location of the critical end point (CEP) on the QCD phase diagram remains a puzzle. Probing the critical phenomena and locating the CEP are the key goals of the beam energy scan (BES) experiments. When approaching the CEP, the long-range correlation is established, and hence leads to a large fluctuation of the conserved charges. In this presentation, we show, based on the...
Phenomenon of bending the trajectory of charged particles in a magnetic field is used as part of the particle tracking and identification system of the ALICE detector at CERN. The detector contains two electromagnets - a large solenoid which generates a magnetic field for the barrel tracking detectors of strength 0.5 Tesla, and a dipole magnet for the Muon Arm Spectrometer which generates a...
The sPHENIX experiment, under construction at Brookhaven National Lab’s Relativistic Heavy Ion Collider, will take first data in 2023, beginning a broad experimental program that will study the emergent properties of QCD in the Quark Gluon Plasma, the structure of jets, and the spin structure of nucleons. The observables that enable these studies require precise tracking provided by three...
The Compressed Baryonic Matter experiment (CBM) at FAIR is designed to explore the
QCD phase diagram at high net baryon densities and moderate temperatures by means of heavy ion collisions with energies from 2-11 AGeV beam energy (Au+Au collisions) and interaction rates up to 10 MHz, provided by the SIS100 accelerator.
Leptons, as penetrating probes not taking part in the strong interaction,...
The Zero Degree Calorimeter (ZDC) at the LHC is primarily a far-forward hadronic calorimeter used to measure spectator neutrons from heavy-ion collisions at the LHC. In addition to spectator neutrons, an electromagnetic module within the ZDC can be used to measure far-forward photons. The Joint ZDC Project (JZCaP) is a collaboration between ATLAS and CMS groups working on R\&D towards an...
Conducting inclusive studies by the ATLAS experiment requires collecting maximally unbiased collision samples. The signature of such a collision is the presence of charged particles tracked down to a very low transverse momentum. In addition, the sample of events with high track multiplicity needs to be enriched in $pp$ and $p$+Pb collisions. In the case of $pp$ collisions, the trigger needs...
The sPNENIX collaboration will start data taking in 2023 at the Relativistic Heavy Ion Collider in BNL to study the Quark-Gluon Plasma and cold-QCD. A detector complex consisting of the solenoid magnet, a hadron calorimeter, an electromagnetic calorimeter, a time projection chamber, a MAPS-based vertex detector, and the intermediate silicon tracker (INTT) is under construction. A tracking...
The sPHENIX detector is being constructed at the Relativistic Heavy Ion Collider (RHIC) at the Brookhaven National Laboratory. It will be commissioned for data taking in 2023. It will focus on measuring jets as well as open and hidden heavy flavor production in heavy ion collisions to study the properties of the Quark Gluon Plasma. To achieve its physics program sPHENIX needs a robust and...
The sPHENIX detector at RHIC is designed to perform high precision measurements of jets and heavy flavor observables to elucidate the microscopic nature of strongly interacting matter. In addition to its electromagnetic calorimeter (EMCal), the sPHENIX calorimeter system includes two hadronic calorimeters (HCals) – the inner HCal (iHCal) and outer HCal (oHCal).
The oHCal (iHCal) are composed...
The Compressed Baryonic Matter experiment (CBM) at FAIR is designed to measure nucleus-nucleus collisions at an unprecedented interaction rate of up to 10MHz which will allow the study of extremely rare probes with high precision. To achieve this high rate capability, CBM will be equipped with fast and radiation-hard detectors, which are readout via a triggerless-streaming data acquisition...
The sPHENIX experiment is currently under construction and will be commissioned for data taking in 2023 at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory. The sPHENIX Event Plane Detector (sEPD) will be a new detector sub-system that can be installed into sPHENIX and deliver measurements of jet quenching anisotropy. The sEPD comprises two scintillator disks, one...
