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

Understand

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.
