Dynamical lattice QCD thermodynamics with domain wall fermions

We present results from simulations of two flavor QCD thermodynamics at Nt = 4 with domain wall fermions. In contrast to other lattice fermion formulations, domain wall fermions preserve the full SUL(Nf )⊗ SUR(Nf) symmetry of the continuum at finite lattice spacing (up to terms exponentially small in an extra parameter). Just above the phase transition, we find that the UA(1) symmetry is broken only by a small amount. We discuss an ongoing calculation to determine the order and properties of the phase transition using domain wall fermions, since the global symmetries of the theory are expected to be important here.
