Effect of parton cascade to medium *

Abstract Jet quenching has been proposed as a probe of the properties of the strongly interacting quark-gluon-plasma in high energy heavy ion collisions. At the meantime, it is also important to study the excitation of medium by propagating jets. Based on Boltzmann equation, a Monte Carlo was constructed to simulate the elastic collisions with thermal partons by energetic jets. Medium modication due to jet-medium interaction has been studied within this model in a uniform medium. Key words jet quenching, parton cascade, medium modication PACS 25.75.-q, 12.38.Mh, 24.10.Lx
