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→μ+μ− decay and the effective Bs 0 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. © 2023 The Author(s)Elsevier B.V.2023Articlehttps://rdlopen.rawdatalibrary.net/r/ebyu/12328https://doi.org/10.1016/j.physletb.2023.1379550370-2693enPhysics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physicsinfo:eu-repo/semantics/openAccessinfo:eu-repo/semantics/articlehttps://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/12328
