Is bottomonium suppression in proton-nucleus and nucleus-nucleus collisions at LHC energies due to the same effects?. J. High Energ. Phys. 2018, 94 (2018). https://doi.org/10.1007/JHEP10(2018)094http://hdl.handle.net/10347/21271We show that we can reproduce all the features of the bottomonium suppression in both proton-nucleus and nucleus-nucleus collisions at LHC energies in a comover-interaction picture. For each collision system, we use the measured relative suppression of the excited ϒ(2S) and ϒ(3S) states to ϒ(1S) by ATLAS and CMS to parametrise the scattering cross sections of all S- and P -wave bottomonia with the comoving particles created during the collisions. In addition to a single nonperturbative parameter, these cross sections depend on the momentum distribution of these comovers which we found to be the same for proton-nucleus and nucleus-nucleus collisions as well as for partonic and hadronic comovers. Moreover, we can also reproduce the absolute suppresion rates measured by ALICE, ATLAS, CMS and LHCb when the nuclear modifications of the parton densities are taken into accounteng© The Authors 2018.
