Abstract
Problem of high PT suppression in RHIC data is generally associated to jet quenching in a dense medium. We recently proposed a new approach to high energy nuclear scattering, which treats the initial stage of heavy ion collisions in a sophisticated way, and whose numerical solution is the model NEXUS. Within this model, there is no jet quenching, but the explicit energy conservation leads to similar results. RHIC high PT ratio between AA and pp results can be reproduced for different centrality bins.
