B_s到μ ^+ μ ^-的LHCb分析

The LHCb analysis for B_s to mu^+ mu^-

Marc-Olivier Bettler

摘要:

LHCb由每年产生的10^12个b-强子支撑,是研究稀有B衰变的绝佳场所。在标准模型中,由中性电流引起的B_s到μ ^+ μ ^-衰变被强烈抑制。然而,如果新物理学(NP)的存在,它的分支比可以显着提高。目前的最佳限制仍然是一个数量级以上的SM预测,从而为观察NP效应留下了空间。在本文中,给出了用于B_s到mu^+ mu^-搜索的当前LHCb分析策略。

英文摘要:

LHCb, bolstered up by the 10^12 b-hadrons produced yearly, is an excellent place to study rare B decays. The B_s to mu^+ mu^- decay, generated by flavour-changing neutral current, is strongly suppressed within the Standard Model (SM). However, its branching ratio can be significantly enhanced if New Physics (NP) exists. The current best limit is still an order of magnitude above the SM prediction, thus leaving room for observation of NP effects. In this document, the current LHCb analysis strategy for the B_s to mu^+ mu^- search is presented.
