Heavy quarks, predominantly produced in hard scattering processes at the initial stages of heavy-ion collisions, are considered as excellent probes to the strongly interacting deconfined medium formed in these collisions. In particular the $D_{s}($c$\bar{s}/\bar{c}$s) production is expected to be affected by both the strangeness enhancement and the primordial charm quark...

Hard jets provide important tools for studying the properties of quark-gluon plasma produced in relativistic heavy-ion collisions. Jet quenching originates a combination of elastic collisions with the medium constituents and medium-induced inelastic processes experienced by the propagating jet partons. In fact, different jet-medium interaction mechanisms play different roles in various jet...

The main goal of the ALICE experiment is the characterization of the Quark Gluon Plasma (QGP), the hot and dense matter created in high-energy nuclear collisions.
Heavy quarks (charm and beauty) are unique probes of the QGP because they are produced in hard partonic scattering processes occurring in the initial stage of the collisions, they propagate through the medium and interact with its...

The large suppression and elliptic flow of heavy-flavor spectra in heavy-ion collisions at RHIC and LHC indicate that heavy quarks couple strongly to the quark gluon plasma (QGP). This feature leads us to seek for a tractable non-perturbative model to study the interactions of heavy quarks in the QGP and connect them to observables. Toward this end, we have developed a many-body T-matrix...

The measurement of heavy flavour production is a powerful tool to study the properties of the high-density QCD medium created in heavy-ion collisions as heavy quarks are sensitive to the transport properties of the medium and may interact with the QCD matter differently from light quarks. In particular, the comparison between the nuclear modification factors of light and heavy flavoured...

Heavy quarks (charm and beauty) are produced through hard parton scatterings in the initial stages of hadronic collisions. The study of their production in pp collisions constitutes a powerful tool to test perturbative QCD calculations at the LHC energies, where a region of phase space at low Bjorken-$x$ can be accessed. Moreover, these measurements provide a reference for the study of nuclear...

We study charm and bottom production in ultra-relativistic heavy-ion collisions by using
the Parton-Hadron-String Dynamics (PHSD) transport approach.
The charm and bottom quarks are produced through initial binary nucleon-nucleon collisions
by using the PYTHIA event generator taking into account the (anti-)shadowing
incorporated in the EPS09 package. The produced heavy quarks interact with...

The quark-gluon plasma (QGP) predicted to have existed in the early universe can be reproduced in heavy-ion collisions at RHIC and the LHC. Rare high energy probes produced in these collisions, which traverse the hot and dense QCD medium, provide an excellent tool to probe this new state of matter. In particular, the medium modification of heavy flavor production cross sections has received...

We address the difficulties of the present theoretical approaches to have a
self-consistent description of the experimental data at both RHIC and LHC.
In particular a puzzling relation between the nuclear modification factor
$R_{AA}(p_T)$ and the elliptic flow $v_2(p_T)$ related to heavy quark has been
observed which challenged existing models. We discuss, comparing different
models and...

The first experimental results from pPb collisions at 5 TeV on the particle yields and azimuthal anisotropies as function of transverse momentum show a very similar behavior in comparison to the observations in heavy-ion collisions, where the quark-gluon plasma (QGP) can be produced. Such pPb results have indeed been explained in the framework of models including a QGP phase such as EPOS3....

The production of charm and beauty quarks in hard parton-parton scattering processes at LHC energies can be described quantitatively by perturbative QCD calculations. Thus the $p_{\rm T}$-differential heavy-flavour cross section in pp collisions can serve as a baseline to gain insight about potential final-state effects in Pb--Pb collisions which modify the $p_{\rm T}$ distribution of...

The energy loss of jets in heavy-ion collisions is expected to depend on the flavor of the fragmenting parton. Thus, measurements of jet quenching as a function of flavor place powerful constraints on the thermodynamical and transport properties of the hot and dense medium. We present recent result on heavy flavor jet spectra and nuclear modification factors of jets associated to charm and...

Recently it has been shown that event-by-event fluctuations are necessary to resolve the long-standing $v_2$ to $R_{AA}$ puzzle for jets. Also, jets in relativistic hydrodynamics can also affect soft physics observables. It is then natural to investigate the effects of full event-by-event fluctuating hydrodynamic backgrounds on the nuclear suppression factor and the elliptic flow of heavy...

Heavy flavor and quarkonium production are important hard probes to test Quantum Chromodynamics (QCD) and measure the properties of the Quark Gluon Plasma (QGP) created in high energy heavy ion collisions. After the installation of the Forward Silicon Vertex Tracker (FVTX) in 2012, the PHENIX experiment collected large data sets of $p$+$p$, $p$+Al, $p$+Au, Cu+Au and Au+Au collisions. The FVTX...

Energetic heavy quarks passing through the hot and dense medium of a quark-gluon plasma (QGP), represented by the resulting mesons, are viewed as a suitable probe for the interactions inside of the QGP, in particular the mechanisms of energy loss, as they are less likely to thermalize within the medium and are mostly created at early stages of the medium evolution.
However, models of both,...

We present the perturbative QCD computation of the heavy quark diffusion constant and
jet quenching parameter in the presence of strong magnetic field at complete leading order (that is, leading log and the constant under the log) in QCD coupling constant.
Azimuthal asymmetries caused by the strong magnetic field in heavy quark diffusion and jet quenching are highlighted.
