"New Prospects for locating the QCD Critical End Point (CEP) at RHIC"

Presented by Roy A. Lacey, Chemistry Department, Stony Brook University

The phase boundaries and the critical end point (CEP) are fundamental
characteristics of hot and dense nuclear matter. Recent experimental
and theoretical evidence for a crossover transition to the quark gluon
plasma in heavy ion collisions at RHIC, have led to a resurgence of
experimental interest in the CEP. The role of stationary state
thermodynamic observables in the search for the CEP is well
known. However, a complimentary set of dynamic observables could play
an even more important role. I will argue that it is possible to
locate the CEP via study of the $\mu_{B}$ and $T$ dependence of both
the specific shear and the bulk viscosities. and give a rudimentary
estimate for the location of the CEP (i.e mu_cep and T_cep) using
existing data.
