We calculate a resummed equation of state with lattice QCD simulations at
imaginary chemical potentials. This work presents a generalization of the
scheme introduced in 2102.06660 to the case of non-zero μS, 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 130MeV≤T≤280MeV. 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 timeslices.Comment: 15 pages, 12 figures; v2: contains ancillary files with tabulated
