  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.
