Özet

Measurements are presented of the Bs 0??+?? branching fraction and effective lifetime, as well as results of a search for the B0??+?? decay in proton-proton collisions at s=13TeV at the LHC. The analysis is based on data collected with the CMS detector in 2016–2018 corresponding to an integrated luminosity of 140fb?1. The branching fraction of the Bs 0??+?? decay and the effective Bs 0 meson lifetime are the most precise single measurements to date. No evidence for the B0??+?? decay has been found. All results are found to be consistent with the standard model predictions and previous measurements.
