Abstract

We calculate spatial correlation functions of in-medium mesons consisting of strange-antistrange, strange-anticharm and charm-anticharm quarks in (2+1)-flavor lattice QCD using the highly improved staggered quark action. A comparative study of the in-medium modifications of mesons with different flavor contents is performed. We observe significant in-medium modifications for the \ensuremathφ and D_s meson channels already at temperatures around the chiral crossover region. On the other hand, for the J/\ensuremathψ and \ensuremathη_c meson channels in-medium modifications remain relatively small around the chiral crossover region and become significant only above 1.3 times the chiral crossover temperature.
