The influence of the Chi_b(3P) state on the decay cascade of bottomium in PbPb collisions at LHC energies

We investigate the decay cascade of the Upsilon(nS) meson including the newly found Chi_b(3P) state in pp and PbPb collisions at LHC energies. The main goal is to quantitatively determine the additional suppression of the Upsilon(nS) states in PbPb collisions relative to pp at LHC energies of sqrt(s_NN) = 2.76 TeV when the Chi_b(3P) state is included together with the Upsilon(nS) and Chi_b(1P,2P) states. It is found that the suppression of Upsilon(1S) in PbPb collisions relative to pp is increased by at most 7% through the inclusion of Chi_b(3P), whereas the suppression factors for the Upsilon(2S) and Upsilon(3S) states do not change significantly.Comment: 4 pages, 2 figure
