NRQCD based S- and P-wave bottomonium spectra at finite temperature from $48^3\times 12$ lattices with $N_f=2+1$ light HISQ flavors

Abstract

We study S-wave and P-wave bottomonium spectral functions at non-zero temperature in 2+1 flavor QCD using the NRQCD formulation for bottom quarks. We use a novel Bayesian approach to reconstruct the spectral functions and find that ${\chi }_{b1}$ survives up to $T=249\mathrm{MeV}$. We also study the effect of different temporal discretizations of the NRQCD formalism on the bottomonium correlation functions
