In relativistic heavy-ion collisions, the production of heavy quarks at large transverse momenta is strongly suppressed compared to proton-proton collisions. In addition an unexpectedly large azimuthal anisotropy was observed for the emission of charmed hadrons in non-central collisions. Both observations pose challenges to the theoretical understanding of the coupling between heavy quarks and the quark-gluon plasma produced in these collisions. Transport models for the evolution of heavy quarks in a QCD medium offer the opportunity to study these effects -two of the most successful approaches are based on the linearized Boltzmann transport equation and the Langevin equation. In this work, we develop a hybrid transport model that combines the strengths of both of these approaches: heavy quarks scatter with medium partons using matrix-elements calculated in perturbative QCD, while between these discrete hard scatterings they evolve using a Langevin equation with empirical transport coefficients to capture the non-perturbative soft part of the interaction. With the hybrid transport model coupled to a state-of-the-art event-by-event bulk evolution model based on 2+1D relativistic viscous fluid dynamics, we study the azimuthal anisotropy and nuclear modification factor of heavy quarks in Pb+Pb collisions at √ s = 5.02 TeV. The parameters of our model are calibrated using a Bayesian analysis comparing to available D-meson and B-meson data at the LHC. Using the calibrated model, we study the implications on heavy-flavor transport properties and predict novel observables. arXiv:1806.08848v1 [nucl-th]

“…Experimental measurements of charm and beauty production in relativistic heavy-ion collisions are a major tool to get information on the properties of the (deconfined, if a sufficiently high energy-density is achieved) medium formed in these events, in particular on the heavy-flavour transport coefficients [1][2][3][4][5][6][7]. At high momentum the major effect of the interaction with the medium is a quenching of the heavy-quark momentum spectra due to parton energy-loss: this provides information on the medium opacity [2,4].…”

We employ the POWLANG transport setup, developed over the last few years, to provide new predictions for several heavy-flavour observables in relativistic heavy-ion collisions from RHIC to LHC center-of-mass energies. In particular, we focus on the development of the flow-harmonics v 2 and v 3 arising from the initial geometric asymmetry in the initial conditions and its associated event-by-event fluctuations. Within the same transport framework, for the sake of consistency, we also compare the nuclear modification factor of the p T spectra of charm and beauty quarks, heavy hadrons and their decay electrons. We compare our findings to the most recent data from the experimental collaborations. We also study in detail the contribution to the flow harmonics from the quarks decoupling from the fireball during the various stages of its evolution: although not directly accessible to the experiments, this information can shed light on the major sources of the final measured effect.

Transport coefficients from in-medium quarkonium dynamics

et al. 2019

The in medium dynamics of heavy particles are governed by transport coefficients. The heavy quark momentum diffusion coefficient, κ, is an object of special interest in the literature, but one which has proven notoriously difficult to estimate, despite the fact that it has been computed by weak-coupling methods at next-to-leading order accuracy, and by lattice simulations of the pure SU(3) gauge theory. Another coefficient, γ, has been recently identified. It can be understood as the dispersive counterpart of κ. Little is known about γ. Both κ and γ are, however, of foremost importance in heavy quarkonium physics as they entirely determine the in and out of equilibrium dynamics of quarkonium in a medium, if the evolution of the density matrix is Markovian, and the motion, quantum Brownian; the medium could be a strongly or weakly coupled plasma. In this paper, using the relation between κ, γ and the quarkonium in medium width and mass shift respectively, we evaluate the two coefficients from existing 2+1 flavor lattice QCD data. The resulting range for κ is consistent with earlier determinations, the one for γ is the first non-perturbative determination of this quantity.
