AbstractWe determine how the yield of large transverse momentum hadrons is modiﬁed due toinduced gluon radiation oﬀ a hard parton traversing a QCD medium. The quenching factoris formally a collinear- and infrared-safe quantity and can be treated perturbatively. In spiteof that, in the p ⊥ region of practical interest, its value turns out to be extremely sensitive tolarge distances and can be used to unravel the properties of dense quark-gluon ﬁnal statesproduced in heavy ion collisions. We also ﬁnd that the standard modelling of quenching byshifting p ⊥ in the hard parton cross section by the mean energy loss is inadequate. 1 Introduction The so-called jet quenching [1–6] is considered an important signal of the production of a newstate of dense matter (quark-gluon plasma) in ultrarelativistic heavy ion collisions. This isunderstood as the suppression of the yield of large transverse momentum jets or particles withrespect to proton-proton collisions.In this paper we concentrate on the quenching eﬀect in inclusive particle spectra, due to theenergy loss by medium induced gluon radiation [7–24].
