论文摘要
Measurements are presented of the B$^0_\mathrm{S}$ $\to$ $μ^+μ^-$ branching fraction and effective lifetime, as well as results of a search for the B$^0$ $\to$ $μ^+μ^-$ decay in proton-proton collisions at $\sqrt{s}$ = 13 TeV at the LHC.该分析基于2016 - 2018年使用CMS检测器收集的数据，对应于140 fb $^{ - 1} $的集成光度。 B $^0_ \ MATHRM {s} $ $ \至$ $ $ $^+μ^ - $ decay和有效的B $^0_ \ Mathrm {S} $ Meson Lifetime是最精确的单个测量值。尚未找到B $^0 $ $ \至$ $ $^+μ^ - $ decay的证据。发现所有结果均与标准模型预测和先前的测量结果一致。
Measurements are presented of the B$^0_\mathrm{S}$ $\to$ $μ^+μ^-$ branching fraction and effective lifetime, as well as results of a search for the B$^0$ $\to$ $μ^+μ^-$ decay in proton-proton collisions at $\sqrt{s}$ = 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 B$^0_\mathrm{S}$ $\to$ $μ^+μ^-$ decay and the effective B$^0_\mathrm{S}$ meson lifetime are the most precise single measurements to date. No evidence for the B$^0$ $\to$ $μ^+μ^-$ decay has been found. All results are found to be consistent with the standard model predictions and previous measurements.
