Production of Υ(nS) mesons in Pb+Pb and pp collisions at 5.02 TeV : = Production of [ypsilon] (nS) mesons in Pb+Pb and pp collisions at 5.02 TeV

Abstract: A measurement of the production of vector bottomonium states, ϒ(1S), ϒ(2S), and ϒ(3S), in Pb+Pb and ⁢ collisions at a center-of-mass energy per nucleon pair of 5.02 TeV is presented. The data correspond to integrated luminosities of 1.38nb−1 of Pb+Pb data collected in 2018, 0.44nb−1 of Pb+Pb data collected in 2015, and 0.26fb−1 of ⁢ data collected in 2017 by the ATLAS detector at the Large Hadron Collider. The measurements are performed in the dimuon decay channel for transverse momentum ⁢ T<30GeV, absolute rapidity | ⁢ ⁢|<1.5, and Pb+Pb event centrality 0–80%. The production rates of the three bottomonium states in Pb+Pb collisions are compared with those in ⁢ collisions to extract the nuclear modification factors as functions of event centrality, ⁢ T, and | ⁢ |. In addition, the suppression of the excited states relative to the ground state is studied. The results are compared with theoretical model calculations
