NRQCD based S and Pwave bottomonium spectra at finite temperature from $48^3 \times 12$ lattices with $N_f=2+1$ light HISQ flavors
Abstract
We study Swave and Pwave bottomonium spectral functions at nonzero 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 $T=249 {\rm MeV}$. We also study the effect of different temporal discretizations of the NRQCD formalism on the bottomonium correlation functions
