Upsilon Suppression at RHIC and LHC in a Modified Colour Screening
Scenario

P. K. Srivastava, S. K. Tiwari, C. P. Singh
The suppression of heavy quarkonia e.g. $J/\psi$, $\Upsilon$ etc. is considered as a suitable probe to identify the nature of the matter created in heavy ion collisions. Recently we have presented a modified colour screening model for $J/\psi$ suppression in the quark gluon plasma (QGP) using quasiparticle model as the equation of state. In this paper, we extend our model to calculate the anomalous suppression of various states of $\Upsilon$ arising due to QGP medium alone. We obtain the suppression patterns of different bottomonia states with respect to centrality at various available collision energies and compare them with the available experimental data.
