Abstract

I compute the thermal suppression of the \ensuremathΥ(1s) and \ensuremathχ_b1 states in √s_NN=2.76 TeV Pb-Pb collisions. Using the suppression of each of these states I estimate the total R_AA for the \ensuremathΥ(1s) state as a function of centrality, rapidity, and transverse momentum. I find less suppression of the \ensuremathχ_b1 state than would be traditionally assumed; however, my final results for the total \ensuremathΥ(1s) suppression are in good agreement with recent preliminary CMS data.
