报告题目："Heavy quark dynamics in heavy-ion collisions: Plasma vs Glasma"
The heavy quarks - charm and bottom, constitutes a unique probe of the Quark Gluon Plasma (QGP) properties. The basic concepts related to thestudy of the dynamics of the heavy quarks in the quark-gluon plasma created in heavy-ion collisions at relativistic energies will be discussed. I shall discuss the difficulties of the present theoretical approach to provide a self-consistentdescription of the experimental data both at BNL-RHIC and CERN-LHC. The importance of the temperature dependence of the drag coefficient on the "heavy quark puzzle" will be discussed. The impact of pre-thermal Glasma phase on heavy quark observable will be discussed and its consequence on "heavy quark puzzle" will be highlighted. Finally I shall present our recent results on heavy quark dynamics in small system produced in p-nucleus collisions at CERN-LHC energy considering a Glasma as well as QGP phase.
Santosh Kumar Das, Ph.D. graduated from Variable Energy Cyclotron Centre in 2012 with the thesis “Heavy Flavor Production and Propagation in Heavy Ion Collision”.
