VOLUME 73 | ISSUE 2 | PAGE 55 On the energy loss of high energy quarks in a finite-size quark-gluon plasma B. G. Zakharov Institut für Kernphysik, Forschungszentrum Jülich, D-52425 Jülich, Germany L. D. Landau Institute for Theoretical Physics RAS, 142432 Chernogolovka, Moscow region, Russia PACS: 12.38.-t Abstract We study within the light-cone path integral approach the induced gluon emission from a fast quark passing through a finite-size QCD plasma. We show that the leading log approximation used in previous studies fails when the gluon formation length becomes of the order of the length of the medium traversed by the quark. Calculation of the energy loss beyond the leading log approximation gives the energy loss which grows logarithmically with quark energy contrary to the energy independent prediction of the leading log approximation.
