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 χ_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
