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

The production cross sections of the Υ(1S), Υ(2S), and Υ(3S) mesons are measured in proton-proton collisions at 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.
