摘要：

In UU collisions at RHIC energies and PbPb collisions at LHC energies the suppression of gamma mesons in the hot quark-gluon medium (QGP) versus reduced feeddown is investigated. Our model encompasses screening, collisional damping and gluo-dissociation in the QGP. For gamma (1S) it is in agreement with both STAR and CMS data provided the relativistic Doppler effect and the reduced feed-down from the gamma (nS) and chi(b)(nP) states are properly considered. At both energies, most of the suppression for the gamma(1S) state is found to be due to reduced feed-down, whereas most of the gamma(2S) suppression is caused by the hot-medium effects. The role of the in-medium effects relative to reduced feed-down increases with energy. The gamma(1S)-suppression in PbPb at root s(NN) = 5.02 TeV is predicted.
