Jet suppression is considered to be a powerful tool to study the properties of a QCD medium created in ultrarelativistic heavy ion collisions. However, theoretical predictions obtained by using jet energy loss in a static QCD medium show disagreement with experimental data, which is known as the heavy flavor puzzle at Relativistic Heavy Ion Collisider (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. We here report a notably improved agreement with the experimental results compared to the static case; this agreement is robust with respect to a realistic range of magnetic mass values. Therefore, the inclusion of dynamical QCD medium effects provides an important step toward understanding the heavy flavor puzzle at RHIC.
