Abstract

We present lattice non-relativistic QCD calculations of bottomonia correlation functions at temperatures T ' 150 − 350 MeV. The correlation functions were computed using extended bottomonia operators, and on background gauge-field configurations for 2+1-flavor QCD having physical kaon and nearly-physical pion masses. We analyzed these correlation functions based on simple theoretically-motivated parameterizations of the corresponding spectral functions. The results of our analyses are compatible with significant in-medium thermal broadening of the ground state S- and P-wave bottomonia.
