Abstract

We study QCD with (2+1)-HISQ fermions at nonzero temperature and nonzero imaginary baryon chemical potential. Monte Carlo simulations are performed using the MILC code along the line of constant physics with a light to strange mass ratio of m_l/m_s=1/20 on lattices up to 48³ × 12 to check for finite cutoff effects. We determine the curvature of the pseudocritical line extrapolated to the continuum limit.
