Abstract

In this talk recent new results from CMS on the search for New Physics effects in heavy flavor decays are presented. Particularly, lepton flavor unification violation was searched for by measuring \(R(K)\) and \(R(J/\psi)\) ratios. Also, lepton flavor violating decay \(\tau\rightarrow 3\mu\) was searched for and upper limit on its branching fraction was extracted. The discussed results were obtained with the RUN II data of pp collisions at \(\sqrt{s}=13\) TeV.

CMS中轻子味普适性违逆的搜索

在这次演讲中，介绍了CMS在重味衰变中寻找新物理效应的最新结果。特别是，通过测量\(R(K)\)和\(R(J/\psi)\)比值来搜索轻子风味统一违反。同时搜索轻子风味违反衰变\(\tau\rightarrow 3\mu\)，提取其分支分数的上限。讨论的结果是用\(\sqrt{s}=13\) TeV的pp碰撞RUN II数据得到的。
