Parton energy loss in the mini quark-gluon plasma and jet quenching in proton-proton collisions

Abstract

We evaluate the medium suppression of light hadron spectra in $pp$ collisions at RHIC and LHC energies in the scenario with formation of a mini quark-gluon plasma. We find a significant suppression effect. For $p_T\sim 10$ GeV we obtained the reduction of the spectra by $\sim [20-30,25-35,30-40]$ % at $\sqrt{s}=[0.2,2.76,7]$ TeV. We also discuss how this phenomenon may change the predictions for the nuclear modification factors for $AA$ and $pA$ collisions.
