Measurement of the B0 s → μ+μ− decay properties and search for the B0 → μ+μ− decay in proton-proton collisions at √s = 13 TeV
Measurements are presented of the B0 s → 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 = 13 TeV at the LHC. The analysis is based on data collected with the CMS detector in 2016–2018 corresponding to an integr...

| Summary: | Measurements are presented of the B0 s → 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 = 13 TeV at the LHC. The analysis is based on data collected with the CMS detector in 2016–2018 corresponding to an integrated luminosity of 140 fb−1. The branching fraction of the B0 s → μ+μ− decay and the effective B0 s 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. |
