Quark Transverse Momentum

The charm quark thermalization in quark-gluon plasma is described by a transport model in relaxation time approximation. Combining the transport equation for charm quarks with the hydrodynamic description for the medium, we calculated the charm quark transverse momentum distribution and discussed its dependence on the relaxation time.

Recent Advances

In this talk we will discuss the recent advances in describing heavy-quark dynamics in the quark-gluon plasma (QGP), which evolves hydrodynamically. Special emphasis is put on the collective flow of the heavy-quarks with the medium constituents, for which we present our latest results obtained within the MC@sHQ+EPOS2 model at √s = 5 TeV.

Abstract Heavy quark production provides a unique probe of the quark-gluon plasma transport properties in heavy ion collisions. Experimental observables like the nuclear modification factor $$R_\mathrm{AA}$$RAA and elliptic anisotropy $$v_\mathrm{2}$$v2 of heavy flavor mesons are sensitive to the heavy quark diffusion coefficient. There now exist an extensive set of such measurements, which allow a data-driven extraction of this coefficient. In this work, we make such an attempt within our recently developed heavy quark transport modeling framework (Langevin-transport with Gluon Radiation, LGR). A question of particular interest is the temperature dependence of the diffusion coefficient, for which we test a wide range of possibility and draw constraints by comparing relevant charm meson data with model results. We find that a relatively strong increase of diffusion coefficient from crossover temperature $$T_c$$Tc toward high temperature is preferred by data. We also make predictions for Bottom meson observables for further experimental tests.
