Diagonal and off-diagonal quark number susceptibilities at high temperatures
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 …
