Thermal Υ(1s) and χb1 Suppression at √(s(NN))=2.76 TeV Pb-Pb collisions at the LHC.
I compute the thermal suppression of the Υ(1s) and χ(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 Υ(1s) state as a function of centrality, rapidity, and transverse momentum. I find less suppression of the χ(b1) state than would be traditionally assumed; however, my final results for the total Υ(1s) suppression are in good agreement with recent preliminary CMS data.
