Description
Quenching of high-$p_T$ hadrons observed in AA collisions is controlled by color transparency, rather than by induced energy loss. This mechanism leads to universality of nuclear suppression, which is confirmed by data for light,
light-heavy mesons, heavy quarkonia and even high-pT protons. Nevertheless,for heavy flavored mesons energy loss turns out to be important, but not the one induced by the dense medium, but vacuum energy loss, i.e. the same as in pp collisions.
