Bottomonium transport in p-Pb and Pb-Pb collisions at energies available at the CERN Large Hadron Collider

We utilize the Boltzmann transport model to investigate the sequential suppression pattern of the & upsih;(1S, 2S, 3S) states in both small (p-Pb) and large (Pb-Pb) collision systems at a center-of-mass energy of root s(NN) = 5.02 TeV. The cold nuclear matter effects occur prior to the formation of bottomonium, which is equivalent for the various bottomonium states & upsih;(1S, 2S, 3S). The sequential suppression pattern of the bottomonium states is regarded as a manifestation of the hot medium effects, where the bottomonium states experience different levels of color screening and parton inelastic scatterings due to their distinct geometrical sizes and binding energies. Excited states of bottomonium are more susceptible to dissociation due to their smaller binding energies. By incorporating both cold and hot medium effects, the transport model provides a consistent explanation for the experimental observations of bottomonium in both small and large collision systems.
