Nuclear Physics & RIKEN Theory Seminar

"Baryonic susceptibilities and Critical behavior in heavy ion collisions"

Presented by Shu Lin, SUNY Stony Brook

Friday, November 20, 2009, 2:00 pm — Small Seminar Room, Bldg. 510

abstract: In the first part of the talk, I will focus on the baryon contribution to the baryonic susceptibilities. Two types of baryons are identified: one is stringy baryons which are chirally insensitive and have a temperature dependent string tension. Its contribution shows a rise and fall near critical temperature. The other is chirally sensitive non-stringy baryons, through which the dependence on quark chemical potential enters the baryonic density of states. In the second part of the talk, I will talk about the existence of critical impact parameter in heavy ion collisions, modeled by gravitational shock wave collision. I will discuss its dependence on energy and saturation scale and comment on its connection with collision of source-free shock waves.
