Executive Summary : | The project focuses on theoretical high energy physics, focusing on the heavy-ion collision experiments at RHIC and LHC, as well as future experiments at FAIR and NICA. The study aims to investigate the dynamics of heavy quarks in the pre-equilibrium stage, which is often overlooked in theoretical calculations. The Glasma phase, described in color glass condensate (CGC) effective theory, is a missing piece in most theoretical calculations, but it significantly affects heavy quark dynamics and other QGP signatures. The project will focus on the heavy quarks' energy loss/gain, the survival probability of various heavy quarkonia states, and the search for stable/unstable modes present in the medium at the Glasma stage. Heavy quarks are chosen as they create during initial hard processes and are considered a noble probe due to their theoretically known and verified distribution. They are too hard to thermalize with the evolving medium, allowing information about their interaction with medium constituents to be carried to the detector end. For RHIC and LHC energies, the research will require working at very high temperatures, while FAIR and NICA energies will require smaller temperatures but high baryonic density. To accommodate these investigations, a framework will be set up to perform these studies at lower temperatures and finite chemical potential. Medium properties such as viscosity, space/momentum anisotropy, and medium particle interactions will be incorporated into the analyses, while experimentally measured observables like the nuclear suppression factor and elliptic flow will be computed within the Langevin approach. Comparing theoretical results with experiments will allow for conclusions on medium properties. |
