Abstract
We calculate a resummed equation of state with lattice QCD simulations at imaginary chemical potentials, generalizing the scheme introduced in our previous work to the case of non-zero μS, and focusing on the line of strangeness neutrality. We present results up to μB/T ≤ 3.5 on the strangeness neutral line 〈S〉 = 0 in the temperature range 130 MeV≤ T ≤ 280 MeV. We also extrapolate the finite baryon density equation of state to small non-zero values of the strangeness-to-baryon ratio R = 〈S〉/〈B〉. We perform a continuum extrapolation using lattice simulations of the 4stout-improved staggered action with 8, 10, 12 and 16 time slices. Finally we test the resummation scheme in a small volume by comparison with direct simulations.
