Heavy-quark colorimetry of QCD matter

Heavy Quark Radiative Energy Loss in QCD Matter

Heavy quark medium induced radiative energy loss is derived to all orders in opacity, (L/λg) . The analytic expression generalizes the GLV opacity expansion for massless quanta to heavy quarks with mass M in a QCD plasma with a gluon dispersion characterized by an asymptotic plasmon mass, mg = gT/ √ 2. Remarkably, we find that the general result is obtained by simply shifting all frequencies in...

QCD and Quark/Hadron Matter

A brief review on the recent theoretical progress in hot/dense QCD is given. Special emphasis is put on the non-perturbative aspects of QCD plasma and the modification of hadron proporties near the critical temperature of chiral transition.

The Heavy Quark Expansion of Qcd

These lectures contain an elementary introduction to heavy quark symmetry and the heavy quark expansion. Applications such as the expansion of heavy meson decay constants and the treatment of inclusive and exclusive semileptonic B decays are included. Heavy hadron production via nonperturbative fragmentation processes is also discussed. 1 Heavy Quark Symmetry In these lectures I will introduce ...

Heavy Quarks and QCD Matter

I present recent results on the theory of QCD matter production in high energy heavy ion collisions and on the interactions of heavy quarks in such environment. The centrality and rapidity dependence of hadron production is evaluated in semi–classical approach. The energy loss of heavy quarks in matter is computed. The heavy–to–light meson ratio (e.g., D/π) at moderate transverse momenta is dem...
