Constraints induced by finite plasma formation time on some physical observables at RHIC

Abstract

We discuss consequences of finite plasma formation time at RHIC. Nuclear modification factor, azimuthal assymetry, di-jet correlations can quantitatively be described by particle production in the early stage of the nuclear collision. A possible impact on interpretation of the non-photonic electrons and J/psi data is also considered.
