$B_s\to μ^{+}μ^{-}$在LHC

$B_s\to μ^{+}μ^{-}$ the at LHC

Nicola Serra

摘要:

ATLAS、CMS和LHCb实验将对超越标准模型(BSM)的物理进行广泛的搜索。美强子衰变的研究是直接BSM搜索的一种替代和补充方法。在$B-$强子衰变中寻找新物理学(NP)的一个特别有希望的观测是对衰变$B_S\to μ^{+} μ^{-}$分支比的测量。这种观察是敏感的物理BSM与新的标量或赝标量有效的运营商,如涉及扩展希格斯部门的理论。本文讨论了ATLAS、CMS和LHCb实验在这方面的应用前景。特别是LHCb实验,由于其良好的粒子识别和动量分辨率,有可能早期发现这种衰变。

英文摘要:

The ATLAS, CMS and LHCb experiments will perform extensive searches for physics Beyond the Standard Model (BSM). The investigation of decays of beauty hadrons represents an alternative and complementary approach to the direct BSM searches. A particularly promising observable for the search of New Physics (NP) in $B-$hadron decays, is the measurement of the branching ratio of the decay $B_S\to μ^{+} μ^{-}$. This observable is sensitive to physics BSM with new scalar or pseudoscalar effective operators, such as theories involving an extended Higgs sector. Here the prospects of the ATLAS, CMS and the LHCb experiments for such a measurement are discussed. In particular the LHCb experiment, thanks to its good particle identification and momentum resolution, has the potential for an early discovery of this decay.
