Analysis of the finite temperature transition for 3 flavor QCD using p4-improved staggered fermions

Abstract

We present a calculation of the transition temperature for 3 flavor QCD using p4-improved staggered fermions with two different variants of fattened links. We examine various susceptibilities at two different values for the temporal extent - $N_t=4$ and $N_t=6$ - in the vicinity of the 3 flavor transition at vanishing chemical potential. For $N_t=4$, we study bare quark masses in the range $m_{q}a=0.005$ to $m_{q}a=0.1$, and for $N_t=6$, we use $m_{q}a=0.02$ to $m_{q}a=0.2$. We also calculate hadron masses and the static quark potential at zero temperature in order to set the scale for the transition temperature and to study quark mass and cut-off dependent scaling properties of the transition temperature. A comparison of the R Algorithm and the RHMC algorithm for finite-temperature simulations is also made
