Bottomonium melting from screening correlators at high temperature

We study the bottomonium screening masses in a $2+1$ flavor QCD on lattice using highly improved staggered quark (HISQ) action. focus wide temperature range region $350\text{ }\text{ }\mathrm{MeV}\ensuremath{\le}T<1000\text{ }\mathrm{MeV}$, and perform our calculations three different spacings corresponding to temporal extent of ${N}_{\ensuremath{\tau}}=8$, 10 12, order control cutoff effects. From detailed dependence we conclude that ${\ensuremath{\eta}}_{b}(1S)$ $\mathrm{\ensuremath{\Upsilon}}(1S)$ states melt at $T>500\text{ while scalar axial-vector ${\ensuremath{\chi}}_{b0}(1P)$ ${h}_{b}(1P)$ already $T>350\text{ }\mathrm{MeV}$.
