标题： 125 GeV Higgs boson decay to a pair of muons in the $μν$SSM

摘要： 最近，ATLAS和CMS合作组测量了125 GeV希格斯玻色子衰变为一对缪子$h\rightarrow \mu \bar{\mu}$，其相对于标准模型（SM）预测的信号强度分别为$1.2\pm0.6$和$1.19^{+0.40+0.15}_{-0.39-0.14}$。 在本工作中，我们研究了125 GeV希格斯玻色子衰变$h\rightarrow \mu \bar{\mu}$在$\mu$中的单环水平，来自$\nu$超对称标准模型（$\mu\nu$SSM）。 与SM预测相比，考虑到来自μ子异常磁偶极矩的约束，$h\rightarrow \mu \bar{\mu}$在$\mu\nu$SSM中的衰变宽度可以提高约10%。 显示英文摘要

摘要： Recently, the ATLAS and CMS Collaborations measured the 125 GeV Higgs boson decay to a pair of muons $h\rightarrow \mu \bar{\mu}$, which reported the signal strength relative to the standard model (SM) prediction is $1.2\pm0.6$ and $1.19^{+0.40+0.15}_{-0.39-0.14}$, respectively. In this work, we investigate the 125 GeV Higgs boson decay $h\rightarrow \mu \bar{\mu}$ at one-loop level in the $\mu$ from $\nu$ Supersymmetric Standard Model ($\mu\nu$SSM). Compared to the SM prediction, the decay width of $h\rightarrow \mu \bar{\mu}$ in the $\mu\nu$SSM can boost up about 10\%, considering the constraint from the muon anomalous magnetic dipole moment.
