Υ Production in Heavy Ion Collisions at LHC

Abstract

We investigate the Υ production in heavy ion collisions at LHC energy in the frame of a dynamical transport approach. Both the initial production and in-medium regeneration and both the cold and hot nuclear matter effects are included in the calculations. In comparison with the ground state Υ(1s), the excited state Υ(2s) is much more sensitive to the heavy quark potential at finite temperature.
