摘要：

We present results for the QCD equation of state, quark densities, and susceptibilities at nonzero chemical potential, using 2 + 1 flavor asqtad ensembles with N-t = 4. The ensembles lie on a trajectory of constant physics for which m(ud) approximate to 0.1m(s). The calculation is performed using the Taylor expansion method with terms up to sixth order in mu/T.
