"Taking a walk with heavy quarks in a field fluctuating Quark-Gluon Plasma
at the LHC energies"

címmel tartandó szemináriumára.


In ultra-relativistic heavy ion collisions, the highly energetic partons are produced in initial partonic subprocesses. Among the produced partons, heavy quarks are mostly produced at the early stage of the collisions from the initial fusion of the partons which makes them a good probe to characterize the QGP. Immediately after their production, these heavy quarks will
propagate through the dense QGP medium and will start loosing energy during their path of travel and as well as will be dragged and diffused in the QGP. These energy loss calculations are usually obtained by considering the QGP medium in an average manner and statistical field fluctuations of the QGP medium are ignored. The QGP being a statistical system of mobile color charge particles, one could characterize it by stochastic electromagnetic field fluctuations.
The effect of this field fluctuations in the QGP leads to an energy gain of the travelling heavy quarks of all momenta and significant at the lower ones.
It is found that this energy gain has some significant effects on the temperature dependent drag and diffusion coefficient of heavy quarks and nuclear modification factor (RAA) of heavy mesons. The results are in good agreement with the experimentally measured RAA of D and B mesons by ALICE and CMS experiments at 2.76 TeV and 5.02 TeV.
