在LHC上伪造TeV量表$W^{\pm}_{R}$的瘦体发育

Falsifying leptogenesis for a TeV scale $W^{\pm}_{R}$ at the LHC

Mansi Dhuria, Chandan Hati, Raghavan Rangarajan, Utpal Sarkar

摘要:

我们指出,发现一个右手带电规范玻色子$W_R^\pm$的质量约为几个TeV,例如通过两个轻子和两个喷流的信号,CMS已经报道该信号具有2.8 $σ$的局部过量,或者通过共振衰减到一对标准模型(SM)规范玻色子中的信号,其显示3.4 $σ$的局部过量(2.5 $σ$全局)报告的ATLAS搜索,将排除所有类的leptogenesis的左-右对称扩展的标准模型(LRSM)与三重态和双重希格斯标量由于不可避免的快速规范介导的$B-L$违反相互作用$e_{R}^{\pm} W_{R}^{\mp} \rightarrow e_{R}^{\mp} W_{R}^{\pm}$。我们的结论是非常一般的,因为它们不一定要求$W_R^\pm$的轻子数违反检测信号。

英文摘要:

We point out that the discovery of a right-handed charged gauge boson $W_R^\pm$ with mass of around a few TeV, for example through a signal of two leptons and two jets that has been reported by CMS to have a 2.8$σ$ local excess or through a signal of a resonance decaying into a pair of standard model (SM) gauge bosons showing a local excess of 3.4$σ$ (2.5$σ$ global) reported by ATLAS search, will rule out all possibilities of leptogenesis in all classes of the left-right symmetric extensions of the Standard Model (LRSM) with both triplet and doublet Higgs scalars due to the unavoidable fast gauge mediated $B-L$ violating interactions $e_{R}^{\pm} W_{R}^{\mp} \rightarrow e_{R}^{\mp} W_{R}^{\pm}$. Our conclusions are very general in the sense that they do not necessarily demand for a lepton number violating detection signal of $W_R^\pm$.
