Parallel Session: Finite Temperature and Density II

Thursday July 1st, 16.40 - 17.00, Room 7

Non--zero density at non--zero temperature

Abstract: There are reasons to believe that the problems encoutered by non--zero baryon density calculations might be lessened at high temperature. I address this point by discussing the performance of the imaginary chemical potential and Glasgow method as a function of temperature in two simplified, interrelated models: four dimensional QCD in the infinite coupling limit, and one dimensional QCD. I use these studies to assess the region of the phase space where imaginary chemical potential/Glasgow method are likely to be successful, and to propose exploratory, but realistic calculations of finite density QCD at high temperature.
