We present a comparative study on the heavy quarks energy loss through medium polarization and gluon radiation in the quark-gluon plasma. To do so, we investigated the energy loss per unit length and drag coefficient for both cases. To have better contrast, we also obtained the nuclear modification factor employing Langevin dynamics. The comparison shows that the polarization effect dominates at lower momentum. The medium temperature also plays an important role in the comparison.

“…There are several theoretical investigations based on various approaches such as semi-classical transport or kinetic, hard-thermal loop (HTL), ASD-CFT, holographic theories have been invoked to study the produced matter [3,4]. There have been several signatures observed that support the formation of the QGP in these experiments such as suppression of heavy quarkonia (a colorless and flavorless bound state of a heavy quark and its antiquark) yields at high transverse momentum, color screening [5][6][7][8], Landau damping [9,10], energy loss or gain of heavy quarks [11][12][13][14][15], etc. The observables that we see at the detector are affected by the presence of the QGP medium that in turn, is influenced by several plasma aspects.…”

The collective modes that are the collective excitations in the hot QCD medium produced in the heavy-ion collision experiments have been studied. These modes being real or imaginary and stable or unstable affect the evolution of the medium. To go into the more profound analysis we incorporated several aspects of the medium such as anisotropy, the presence of medium particle collisions, and finite baryonic chemical potential. The first two facets have been studied several times from different perspectives but the inclusion of finite chemical potential is a missing part. Therefore, to have a close analysis, we have combined these effects. The medium particle collision has been included using BGK-collisional kernel, the anisotropy, and finite chemical potential enter via quarks, anti-quarks and gluons distribution functions. Our results indicate that the presence of finite chemical potential enhances the magnitude of unstable modes which may affect the fast thermalization of the hot QCD medium. Moreover, it is interesting to see the consequences of finite chemical potential along with the other aspects of the created medium from the viewpoint of low-energy heavy-ion collision experiments that operate at low temperatures and finite baryon density.

We study the heavy quark energy loss in the presence of a background magnetic field. The analysis considers the high magnetic field generated by spectators from initial hard collisions that were incorporated using the medium-modified Debye mass, determined from quark condensates at finite temperature and magnetic field via recent lattice quantum chromodynamics (LQCD) calculations. We analyse the impact of medium polarization on the heavy quark propagation in a quark-gluon plasma formed in relativistic heavy-ion colliders like RHIC and LHC. For simplification, we considered the static medium with constant temperature and magnetic field values. Then, we explore the nuclear modification factor ($R_{AA}$) at different magnitudes of magnetic field strengths at fixed temperatures. The energy loss of heavy quarks significantly increases, leading to $R_{AA}$ suppression at higher magnetic field values.
