The suppression of charmonia production in high energy nuclear collisions relative to proton-proton collisions due to the color screening was proposed as a signature of the formation of Quark-Gluon Plasma. However, there are other effects that may affect the observed...

We report on measurements of Upsilon mesons in the dielectron channel with the STAR detector at RHIC.
Upsilon mesons are expected to be sensitive to the deconfinement transition in the Quark Gluon Plasma, and
to be useful in determining the medium temperature. We compare the yield obtained in Au+Au data,
separated into three centrality classes, to the measured cross section from p+p...

The nuclear modification of quarkonia in heavy ion collisions involves a set of physics parameters like energy density, path length and initial state effects which can be controlled experimentally with variations in the beam energy, use of different species and rapidity ranges. The PHENIX detector recently collected high statistics data using combinations of heavy ion species and beam...

Based on the Parton-Hadron-String Dynamics (PHSD) transport approach
we study the suppression pattern of charmonia at SPS and RHIC with
respect to centrality and rapidity employing various model concepts
such as variants of the `comover absorption' model or the `charmonium melting' scenario. A detailed comparison to the RHIC experimental data demonstrates that non-hadronic interactions are...
