We suggest that the combined effect of screening, gluon-induced dissociation, collisional damping, and reduced feed-down explains most of the sequential suppression of Υ(nS) states that has been observed in PbPb relative to pp collisions at √ sNN = 2.76 TeV. The suppression is thus a clear, albeit indirect, indication for the presence of a QGP. The Υ(1S) ground state suppression is essentially due to reduced feed-down, collisional damping and gluodissociation, whereas screening prevails for the…

The effect of temperature gradient on the heavy quark–antiquark potential using a gravity dual model

Thermal systems have traditionally been modeled via Euclideanized space by analytical continuation of time to an imaginary time. We extend the concept to static thermal gradients by recasting the
