Parallel Session IV: Heavy Flavor (IV)
- Hua Pei (Central China Normal University CCNU (CN))
ATLAS has measured the production of heavy flavor muons in 2.76 TeV pp and Pb+Pb collisions at the LHC. The measurements are performed over the transverse momentum range 4 < pT < 14 GeV and for five Pb+Pb centrality intervals. Backgrounds arising from in-flight pion and kaon decays, hadronic showers, and mis-reconstructed muons are statistically removed using a template fitting procedure....
We evaluate open heavy-flavor (HF) transport in relativistic heavy-ion
collisions utilizing a strong-coupling treatment for both macro- and
micro-dynamics of the problem [1]. The former is realized through a
hydrodynamic evolution quantitatively constrained by bulk-hadron spectra
and elliptic flow. The HF transport is based on non-perturbative $T$-matrix
calculations of heavy-light parton...
Heavy quarks are predominantly produced at early stages of high-energy heavy-ion collisions due to their large masses, and thus experience the whole evolution of the Quark-Gluon Plasma (QGP). Studies of interactions between heavy quarks and the QGP can provide new insights to the properties of the QGP. Heavy quark production measured in p+p collisions serves as a baseline to similar...
We discuss heavy-quark dynamics in the quark-gluon plasma under a strong magnetic field induced by colliding nuclei. By the use of the diagrammatic resummation techniques for Hard Thermal Loop and the external magnetic field, we show analytic results of heavy-quark diffusion constant and drag force which become anisotropic due to the preferred spatial orientation in the magnetic field. We...
