摘要：

The bottomonium states due to their varying binding energies dissolve at different temperatures and thus their nuclear modification factors and relative yields have potential to map the properties of Quark-Gluon Plasma (QGP). We estimate the suppression of bottomonia states due to color screening in an expanding QGP of finite lifetime and size with the conditions relevant for PbPb collisions at Large Hadron Collider. The properties of Upsilon states and recent results on their dissociation temperatures have been used as ingredients in the study. The nuclear modification factors and the ratios of yields of Upsilon states are then obtained as a function of transverse momentum and centrality. We compare our theoretical calculations with the bottomonia yields measured with CMS in PbPb collisions at root s(NN) - 2.76 TeV. The model calculations explain the data very well.
