摘要：

We investigate the Upsilon 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 Upsilon (1s), the excited state Upsilon(2s) is much more sensitive to the heavy quark potential at finite temperature. (C) 2014 Elsevier B.V. All rights reserved.
