Deriving the existence of $B\bar{B}^*$ bound states from the X(3872) and Heavy Quark Symmetry
Deriving the existence Heavy Quark Symmetry
2011/7/21
We discuss the possibility and the description of bound states between $B$ and $\bar{B}^*$ mesons. We argue that the existence of such a bound state can be deduced from (i) the weakly bound X(3872) st...
Heavy-Quark Diffusion and Hadronization in Quark-Gluon Plasma
Heavy Quark Diffusion Quark Gluon Plasma Quark Recombination
2011/7/20
We calculate diffusion and hadronization of heavy quarks in high-energy heavy-ion collisions implementing the notion of a strongly coupled quark-gluon plasma in both micro- and macroscopic components....

2011/1/7
We study the quark mass dependence of the QCD phase transition by an effective potential defined through the distribution function of observables. As a test of the method, we study the first order dec...

The cross section for exclusive heavy quark and heavy antiquark pair (Q¯Q) production in periph-eral ultrarelativistic heavy ion collisions is calculated for the LHC energy √sNN = 5.5 TeV. Here w...
