Abstract
Measurements are presented of the B s 0→μ +μ − branching fraction and effective lifetime, as well as results of a search for the B 0→μ +μ − 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 B s 0→μ +μ − decay and the effective B s 0 meson lifetime are the most precise single measurements to date. No evidence for the B 0→μ +μ − decay has been found. All results are found to be consistent with the standard model predictions and previous measurements.
