Quick view on jet tomography at RHIC energies

Abstract A strong suppression of π production in AuAu collision was discovered at RHIC energies in the high- p T region. The lack of this suppression in dAu collision proved that this effect can be connected to final state effects, namely medium-induced jet energy loss caused by dense color matter. Here we display our quantitative results on jet quenching in AuAu collisions using our pQCD-based parton model calculations. In parallel we present results on dAu collision.
