QCD equation of state at non-zero chemical potential

Understand

We present our new results for the QCD equation of state at nonzero chemical potential at N_t=6 and compare them with N_t=4.

• We use the Taylor expansion method with terms up to sixth order in simulations with 2+1 flavors of improved asqtad quarks along a line of constant physics with m_l=0.1 m_s and approximately physical strange quark mass m_s.
