Bottomonium transport in p-Pb and Pb-Pb collisions at the LHC
arXiv:2304.03929 · doi:10.1103/PhysRevC.108.014901
Abstract
We employ the Boltzmann transport model to study the sequential suppression pattern of states in both small (p-Pb) and the large (Pb-Pb) collision systems at TeV. The cold nuclear matter effects happen before the formation of bottomonium, which is the same for different bottomonium states . The sequential suppression pattern of bottomonium states is treated as a signal of the hot medium effects, where bottomonium states suffer different magnitudes of the color screening and parton inelastic scatterings due to their different geometry sizes and binding energies. Bottomonium excited states are more easily dissociated with smaller binding energy via the final-state interactions. Including both cold and hot medium effects, transport model consistently explains the experimental data about bottomonium in both small and large collision systems.
