Bulk Thermodynamics at non-vanishing baryon density

Presenter: Miao Chuan — Fakultät für Physik, Universität Bielefeld

C. Miao for the RBC-Bielefeld Collaboration

We will present results of a lattice simulation of 2+1 flavor QCD using p4-improved staggered fermions. The simulations were carried out for a realistic strange quark mass and up and down quark masses fine tuned so that the pseudo scalar pion mass is around 200 MeV. The tempral extents of the lattices are up to 6. We have studied the bulk thermodynamics (pressure, baryon number density etc.) at finite temperature and small chemical potentials µu, µs via Taylor expansion.
