Measurement of the Υ(1S), Υ(2S), and Υ(3S) differential cross sections in pp collisions at $$ \sqrt{s}=13.6 $$ TeV

A bstract The production cross sections of the Υ(1S), Υ(2S), and Υ(3S) mesons are measured in proton-proton collisions at $$ \sqrt{s}=13.6 $$ s = 13.6 TeV, using a data sample collected in 2022 by the CMS experiment and corresponding to an integrated luminosity of 37.4 fb − 1 . The measurement is performed in the μ + μ − decay channels, differentially as a function of transverse momentum in the 20–200 GeV range, in the | y | 0 . 6 and 0 . 6 | y | 1 . 2 rapidity intervals.
