Jet suppression of pions and single electrons at Au+Au collisions at RHIC

Abstract

Jet suppression is considered to be a powerful tool to study the properties of a QCD medium created in ultra-relativistic heavy ion collisions. However, theoretical predictions obtained by using jet energy loss in static QCD medium show disagreement with experimental data, which is known as the heavy flavor puzzle at RHIC. We calculate the suppression patterns of pions and single electrons for Au+Au collisions at RHIC by including the energy loss in a finite size dynamical QCD medium, with finite magnetic mass effects taken into account. In contrast to the static case, we here report a good agreement with the experimental results, where this agreement is robust with respect to magnetic mass values. Therefore, the inclusion of dynamical QCD medium effects provides a reasonable explanation of the heavy flavor puzzle at RHIC.
