title = "Measurement of the multiplicity dependence of G production ratios in pp collisions at vs=13 Tev",
abstract = "The Gamma(2S) and Gamma(3S) production cross-sections are measured relative to that of the Gamma(1S) meson, as a function of charged-particle multiplicity in proton-proton collisions at a centre-of-mass energy of 13TeV. The measurement uses data collected by the LHCb experiment in 2018 corresponding to an integrated luminosity of 2 fb(-1). Both the Gamma(2S)to-Gamma(1S) and Gamma(3S)-to-Gamma(1S) cross-section ratios are found to decrease significantly as a function of event multiplicity, with the Gamma(3S)-to-Gamma(1S) ratio showing a steeper decline towards high multiplicity. This hierarchy is qualitatively consistent with the comover model predictions, indicating that final-state interactions play an important role in bottomonia production in high-multiplicity events.",
