Abstract

We present continuum extrapolated lattice QCD results for up to fourth-order diagonal and off-diagonal quark number susceptibilities in the high temperature region of 300–700 MeV. Lattice QCD calculations are performed using $2 + 1$ flavors of highly improved staggered quarks with nearly physical quark masses and at four different lattice spacings. Comparisons of our results with recent weak coupling calculations yield reasonably good agreements for the entire temperature range.
