Energy loss of high energy quark and gluon jets penetrating dense matter produced in ultrarelativistic heavy ion collisions leads to jet quenching and thus probes the quark-gluon plasma formed in those reactions [1,2]. The non-abelian radiative energy loss, ∆E(E, L), suppresses the moderate 2−3 GeV < pT < 10−15 GeV distributions of hadrons in a way that can also influence the jet fragmentation ...
