Abstract

A new scenario, alternative to energy loss, for the observed suppression of high-pT hadrons observed at RHIC is proposed. In the limit of a very dense medium crated in nuclear collisions the mean free-path of the produced (pre)hadron vanishes, and and the nuclear suppression, R_AA is completely controlled by the production length. The RHIC data are well explained in a parameter free way, and predictions for LHC are provided.
