论文摘要
衰减B $^+$ $ \至$ k $^*$（892）$^+μ^+μ^ - $的角度分布使用$ \ sqrt {s} = $ 8 tev Proton-proton中的CMS检测器收集的事件进行了研究，该事件对应于LHC的LHC，对应于20.0.0 fb $^$^$^ - 1 fb $^ - 1 fb $^ - 1 fb。 MUON的前向不对称和K $^*$（892）$^+$介入的纵向极化是根据Dimuon不变质量平方的函数确定的。这些是这种独家衰减模式的第一个结果，并且与标准模型预测一致。
Angular distributions of the decay B$^+$ $\to$ K$^*$(892)$^+μ^+μ^-$ are studied using events collected with the CMS detector in $\sqrt{s} =$ 8 TeV proton-proton collisions at the LHC, corresponding to an integrated luminosity of 20.0 fb$^{-1}$. The forward-backward asymmetry of the muons and the longitudinal polarization of the K$^*$(892)$^+$ meson are determined as a function of the square of the dimuon invariant mass. These are the first results from this exclusive decay mode and are in agreement with a standard model prediction.
