Novel mechanism for suppression of heavy flavored mesons in h eavy ion collisions
Original language description
Production of haevy flavored hadrons from fragmentation of heavy quarks represents an alternative way for study of manifestations and properties of a medium created after heavy ion collisions. The observed strong suppression of heavy flavored D and B mesons, produced with high transverse momenta pT, is caused by final state interactions with the created dense medium. The space-time pattern of hadronization of a highly virtual heavy quark is controlled by its vacuum radiation, which is ceased at a short time scale in accordance with perturbative QCD calculations and LEP measurements of the fragmentation functions. However, the production of a heavy flavored hadrons lasts a long time scale due to prompt multiple breakups of these hadrons caused by the medium. This fact together with the specific shape of the heavy quark fragmentation functions allow to explain a strong suppression of D and B heavy mesons in a good accord with available data
