Parallel Session 8.4: Open Heavy Flavors (III)
- Roberta Arnaldi (Universita e INFN Torino (IT))
Heavy quarks are useful probes of nuclear matter since at RHIC energies as they are produced only in initial parton collisions, and thus are sensitive to effects at all stages of the collisions. Because of their large mass, b quarks are expected to lose less energy through gluon radiation than lighter quarks. $J/\psi$ production from the $B \rightarrow J/\psi$ decay is a powerful observable...
Beauty production and phenomena in heavy-ion collisions are considered to be one of the key measurements to address the flavour-dependence of in-medium energy loss in PbPb collisions at the LHC. The CMS experiment has excellent capabilities for measuring b-quark production thanks to the excellent performances of its muon and tracker system, allowing the measurement of $D^{0}$ and J/$\Psi$...
Despite intense theoretical and experimental investigation, the physical mechanisms governing the suppression of bound quark-antiquark states in nuclear collisions are not yet fully understood. While color screening in a plasma phase is expected to play a role, there are numerous other possible suppression mechanisms that do not require deconfinement, as well as effects on the heavy quark...
It has recently been argued that event-by-event fluctuations, choice in initial conditions, and proper calculations of $v_2\{2\}$ are necessary to resolve the long-standing $R_\text{AA}$ to $v_2\{2\}$ puzzle for high $p_T$ identified hadrons [1,2]. Here we investigate the effects of full event-by-event fluctuating hydrodynamic backgrounds on the nuclear suppression factor and flow harmonics...
Heavy quarks are considered as valuable probes of the quark-gluon plasma (QGP) created in ultra-realistic heavy-ion collisions. However, the simultaneous description of the heavy meson nuclear modification factor $R_{AA}$ and the elliptic flow $v_2$ poses a significant challenge for most commonly used transport modes, especially those based on Langevin transport. We propose a generalized...
Heavy-flavor observables are excellent probes of the properties of the in-medium interactions, the medium properties and the degrees of freedom of the quark-gluon plasma created in heavy-ion collisions. Progressing toward a quantitative description, we describe, in EPOSHQ, the dynamics of heavy quark coupled systematically to the EPOS3 model: heavy-quarks are produced from the EPOS3 flux tube...
