We note, however, that most of the papers above have only worked at what we would call leading order in HTLpt.…”

We calculate the three-loop thermodynamic potential of QCD at finite temperature and chemical potential(s) using the hard-thermal-loop perturbation theory (HTLpt) reorganization of finite temperature and density QCD. The resulting analytic thermodynamic potential allows us to compute the pressure, energy density, and entropy density of the quark-gluon plasma. Using these we calculate the trace anomaly, speed of sound, and second-, fourth-, and sixth-order quark number susceptibilities. For all observables considered we find good agreement between our three-loop HTLpt calculations and available lattice data for temperatures above approximately 300 MeV.

“…For low energy heavy quarks, the dominant energy loss mechanism is the collision of the heavy quark with the constituents of the QGP (see, for example, Refs. [5][6][7][8][9][10][11][12][13][14]). We calculate the collisional energy loss of a heavy quark traversing the QGP including the effects of a finite relaxation time τ π on the energy loss.…”

“…Achieving a deep understanding of the phenomenon of quark energy loss in the quark-gluon plasma (QGP) is of crucial importance for the correct interpretation of data on hadron suppression at the Relativistic Heavy Ion Collider (RHIC) and the Large Hadron Collider (LHC), as well as for gaining insight on the thermalization process of matter created in these experimental facilities [1][2][3][4][5][6][7][8][9][10].…”

Heavy quark collisional energy loss in the quark-gluon plasma including finite relaxation time

In this paper, we calculate the soft-collisional energy loss of heavy quarks traversing the viscous quark-gluon plasma including the effects of a finite relaxation time τπ on the energy loss. We find that the collisional energy loss depends appreciably on τπ. In particular, for typical values of the viscosity-to-entropy ratio, we show that the energy loss obtained using τπ = 0 can be ∼ 10% larger than the one obtained using τπ = 0. Moreover, we find that the energy loss obtained using the kinetic theory expression for τπ is much larger that the one obtained with the τπ derived from the Anti de Sitter/Conformal Field Theory correspondence. Our results may be relevant in the modeling of heavy quark evolution through the quark-gluon plasma.

“…Nevertheless this approach does not take into account the chromo-electric field fluctuations and the particle recoil in the plasma. To include these effects one needs to perform two kind of averaging [30]: (a) an ensemble average with respect to the equilibrium density matrix and (b) a time average over random fluctuations in the plasma. This averaging is applicable to high energy jets of both the light and heavy quarks in the QGP.…”

Effect of the chromo-electromagnetic field fluctuations on heavy quark propagation in a deconfined hadronic medium at energies available at the CERN Large Hadron Collider

We consider the effect of the chromo-electromagnetic field fluctuations in addition to the collisional as well as the radiative energy losses suffered by heavy quarks while propagating through the hot and dense deconfined medium of quarks and gluons created in relativistic heavy ion collisions. The chromo-electromagnetic field fluctuations play an important role as they lead to an energy gain of heavy quarks of all momenta and are significant at low momentum. We include the effect of these fluctuations, for the first time, while computing the nuclear modification factor (R AA ) of heavy mesons, viz., D mesons and B mesons, and compare with the experimental measurements in Pb-Pb collisions at √ s NN = 2.76 and 5.02 TeV by the CMS and ALICE experiments at the CERN Large Hadron Collider. Our results are found to be in very good agreement with the measurements.
