“…In the right panel of figure 9, the average D-meson R AA for the 10% most central Pb-Pb collisions is compared to the D 0 nuclear modification factor measured by the STAR Collaboration for the 10% most central Au-Au collisions at √ s NN = 200 GeV [31].

“…This feature is described by heavy-flavour transport calculations that include radial flow and a contribution due to recombination in the charm hadronisation process [31]. A first measurement of the production of prompt D mesons at mid-rapidity in the p T interval 2-16 GeV/c was published, using the Pb-Pb data at √ s NN = 2.76 TeV collected in 2010 during LHC Run 1 [32].…”

“…The MC@sHQ+EPOS model has recently improved the description of the R AA in the p T interval 2-8 GeV/c including the EPS09 shadowing parameterisation in addition to in-medium energy loss, the TAMU elastic model overestimates the R AA in central collisions in the p T interval 6-30 GeV/c and the POWLANG model underestimates it in the interval 5-36 (8-16) GeV/c in the 0-10% (30-50%) centrality class. Interestingly, these model calculations provide a fair description of the D-meson v 2 measured at LHC [35] and of the D-meson R AA measured at RHIC [31]. On the other hand, the model calculations that do not include a hydrodynamical medium expansion and hadronisation via recombination, namely Djordjevic, Vitev, WHDG -and as a consequence do not describe the features observed for the v 2 at the LHC and the R AA at RHIC in the momentum region up to about 3-5 GeV/c -provide a good description of the R AA in the full "high p T interval", above 5 GeV/c.…”

The production of prompt charmed mesons D 0 , D + and D * + , and their antiparticles, was measured with the ALICE detector in Pb-Pb collisions at the centre-of-mass energy per nucleon pair, √ s NN , of 2.76 TeV. The production yields for rapidity |y| < 0.5 are presented as a function of transverse momentum, p T , in the interval 1-36 GeV/c for the centrality class 0-10% and in the interval 1-16 GeV/c for the centrality class 30-50%. The nuclear modification factor R AA was computed using a proton-proton reference at √ s = 2.76 TeV, based on measurements at √ s = 7 TeV and on theoretical calculations. A maximum suppression by a factor of 5-6 with respect to binary-scaled pp yields is observed for the most central collisions at p T of about 10 GeV/c. A suppression by a factor of about 2-3 persists at the highest p T covered by the measurements. At low p T (1-3 GeV/c), the R AA has large uncertainties that span the range 0.35 (factor of about 3 suppression) to 1 (no suppression). In all p T intervals, the R AA is larger in the 30-50% centrality class compared to central collisions. The D-meson R AA is also compared with that of charged pions and, at large p T , charged hadrons, and with model calculations. The ALICE collaboration 36 IntroductionA state of strongly-interacting matter characterised by high energy density and temperature is predicted to be formed in ultra-relativistic collisions of heavy nuclei. According to calculations using Quantum Chromodynamics (QCD) on the lattice, these extreme conditions lead to the formation of a Quark-Gluon Plasma (QGP) state, in which quarks and gluons are deconfined, and chiral symmetry is partially restored (see e.g. [1][2][3][4]). Heavy quarks are produced in the hard scattering processes that occur in the early stage of the collision between partons of the incoming nuclei. Their production is characterised by a timescale ∆t < 1/(2 m c,b ), ∼ 0.1 fm/c for charm and ∼ 0.01 fm/c for beauty quarks, that is shorter than the formation time of the QGP medium, about 0.3 fm/c at Large Hadron Collider (LHC) energies [5]. They can successively interact with the constituents of the medium and lose part of their energy, via inelastic processes (gluon radiation) [6,7] or elastic scatterings (collisional processes) [8][9][10]. Energy loss can be studied using the -1 - JHEP03(2016)081nuclear modification factor R AA , which compares the transverse-momentum (p T ) differential production yields in nucleus-nucleus collisions (dN AA /dp T ) with the cross section in proton-proton collisions (dσ pp /dp T ) scaled by the average nuclear overlap function ( T AA )· dN AA /dp T dσ pp /dp T .(1.1)The average nuclear overlap function T AA over a centrality class is proportional to the number of binary nucleon-nucleon collisions per A-A collision in that class and it can be estimated via Glauber model calculations [11,12]. According to QCD calculations, quarks are expected to lose less energy than gluons because their coupling to the medium is smaller [6,7]. In the energy regime of the...

“…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].…”

“…At low/intermediate momenta, on the other hand, if the transport coefficients were large enough, heavy quarks would even approach local thermal equilibrium with the rest of the medium, taking part in its collective expansion [8]. This would lead to clear signatures in the final observables: the radial and elliptic flow of the fireball arising from the heavyion collision would leave their fingerprints also in the heavy-flavour sector, boosting the heavy quarks from low to moderate momenta and giving rise to azimuthal anisotropies in their angular distributions [3,5]. Furthermore, since nowadays higher flow-harmonics (v 3 , v 4 , v 5 .…”

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.
