Thermodynamics of (2+1)-flavor QCD

TL;DR

This paper presents results on the thermodynamics of (2+1)-flavor QCD, including susceptibilities, potential, and string tension, using lattice simulations near realistic quark masses.

Contribution

First lattice QCD study to compute multiple thermodynamic quantities with 2+1 flavors at near-physical quark masses.

Findings

Calculated susceptibilities of chiral condensate and Polyakov loop

Determined static quark potential and spatial string tension

Performed on QCDOC and APEnext supercomputers

Abstract

We report on the status of our QCD thermodynamics project. It is performed on the QCDOC machine at Brookhaven National Laboratory and the APEnext machine at Bielefeld University. Using a 2+1 flavor formulation of QCD at almost realistic quark masses we calculated several thermodynamical quantities. In this proceeding we show the susceptibilites of the chiral condensate and the Polyakov loop, the static quark potential and the spatial string tension.
