Hard QCD processes in ultrarelativistic heavy-ion collisions becomeincreasingly relevant and they can be used as probes of the dense matter formedduring the violent scatterings. We will discuss how one can use these hardprobes to study the properties of the dense matter and the associatedphenomenologies. In particular, we study the effect of jet quenching due tomedium-induced energy loss on inclusive particle $p_T$ distributions andinvestigate how one can improve the measurement of parton energy loss in directphoton eventsComment: Talk given at the International School on Physics of the Quark Gluon Plasma, Hiroshima, June 3-6, 1997 and the 5th International Workshop on Relativistic Aspects of Nuclear Physics, Rio de Janeiro, August 27-29. 17 pages with 9 ps figure
