The analysis is based on an event sample of proton-proton collisions at a center-of-mass energy of 13 TeV, collected by the CMS experiment in 2018 and corresponding to an integrated luminosity of (Formula presented). Normalizing to the (Formula presented) decay mode leads to a branching fraction of (Formula presented), a value that is consistent with the standard model prediction. © 2024 CERN, for the CMS Collaboration.American Physical Society2024Articlehttps://rdlopen.rawdatalibrary.net/r/ebyu/11526https://doi.org/10.1103/physrevd.109.l1111012470-0010enPhysical Review Dinfo:eu-repo/semantics/openAccessinfo:eu-repo/semantics/articlehttps://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/11526
