Heavy Quark Dynamics in the QGP
We assess transport properties of heavy quarks in the Quark-Gluon Plasma (QGP) that show a strong non-perturbative behavior. A T-matrix approach based on a potential taken from lattice QCD hints at the presence of heavy-quark (HQ) resonant scattering with an increasing strength as the temperature, T , reaches the critical temperature, Tc ' 170 MeV for deconfinement from above. The implementatio...
متن کاملLangevin + Hydrodynamics Approach to Heavy Quark Propagation and Correlation in QGP
We develop a relativistic Langevin dynamics under the background of strongly interacting quarkgluon fluid described by the (3+1)-dimensional hydrodynamics. The drag force acting on charm and bottom quarks is parametrized according to the formula obtained from the anti-de-Sitter space/conformal field theory (AdS/CFT) correspondence. In this setup, we calculate the nuclear modification factor RAA...
متن کاملHeavy-Quark Spectra at RHIC and Resonances in the QGP
Thermalization and collective flow of charm (c) and bottom (b) quarks are evaluated from elastic parton scattering via “D”and “B”-meson resonances in an expanding, strongly interacting quark-gluon plasma at RHIC. Pertinent drag and diffusion coefficients are implemented into a relativistic Langevin simulation to compute transverse-momentum spectra and azimuthal flow asymmetries (v2) of cand b-q...
متن کاملHeavy-Quark Kinetics in the QGP at LHC
We present predictions for the nuclear modification factor and elliptic flow of D and B mesons, as well as of their decay electrons, in semicentral Pb-Pb collisions at the LHC. Heavy quarks are propagated in a Quark-Gluon Plasma using a relativistic Langevin simulation with drag and diffusion coefficients from elastic interactions with light anti-/quarks and gluons, including non-perturbative r...
متن کاملT-matrix approach to heavy quark diffusion in the QGP
We assess transport properties of heavy quarks in the Quark-Gluon Plasma (QGP) using static heavy-quark (HQ) potentials from lattice-QCD calculations in a Brueckner many-body T -matrix approach to evaluate elastic heavy-quark-light-quark scattering amplitudes. In the attractive meson and diquark channels resonance states are formed for temperatures up to ∼1.5Tc, increasing pertinent drag and di...
