摘要：

LHC实验将对标准模型（BSM）之外的物理进行敏感的测试。除了直接的BSM搜索，美强子衰变的调查代表了另一种方法。ATLAS和CMS的工作集中在那些已经在第一和第二级触发时可以有效选择的B-衰变上。最有利的触发信号将是$B$ -强子衰变与μ子在最后状态。使用这个触发器，ATLAS和CMS将能够适应罕见衰变部门前所未有的高统计数据。这些是纯粹的双μ子衰变，以及半μ子独占通道的家族。已经有了对应于\ensuremath{1 fb^{-1}}的积分亮度的数据，双μ子通道的灵敏度将与目前的测量（世界平均值）相当。我们的策略是在LHC的名义光度下进行双μ子通道计划。特别地，具有\ensuremath{\sim} 5 sigma显著性的\ensuremath{B_s \to μμ}信号可以结合低光度\ensuremath{10^{33}cm^{-2} s^{-1}}样本与在光度为\ensuremath {10^{34}cm^{-2} s^{-1}的LHC运行一年的样本来测量。

英文摘要：

The LHC experiments will perform sensitive tests of physics beyond the Standard Model (BSM). The investigation of decays of beauty hadrons represents an alternative approach in addition to direct BSM searches. The ATLAS and CMS efforts concentrate on those B-decays that can be efficiently selected already at the first and second level trigger. The most favorable trigger signature will be for $B$-hadron decays with muons in the final state. Using this trigger, ATLAS and CMS will be able to accommodate unprecedentedly high statistics in the rare decay sector. These are purely dimuon decays, and families of semimuonic exclusive channels. Already with data corresponding to an integrated luminosity of \ensuremath{1 fb^{-1}}, the sensitivity in the dimuon channels will be comparable to present measurements (world average). The strategy is to carry on the dimuon channel program up to nominal LHC luminosity. In particular the \ensuremath{B_s \to μμ} signal with \ensuremath{\sim}5 sigma significance can be measured combining low luminosity \ensuremath{10^{33}cm^{-2} s^{-1}} samples with those of one year of LHC operation at a luminosity of \ensuremath{10^{34}cm^{-2} s^{-1}
