Measurements are presented of the B_s⁰ → μ⁺μ^- branching fraction and effective lifetime, as well as results of a search for the B⁰ → 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_s⁰ → μ⁺μ^- decay and the effective B_s⁰ meson lifetime are the most precise single measurements to date. No evidence for the B⁰ → μ⁺μ^- decay has been found. All results are found to be consistent with the standard model predictions and previous measurements.
