摘要引入新的标量三重态来赋予轻子质量,使得夸克与轻子有不同的质量起源.模型中的中性标量粒子有助于改善μ子反常磁矩的实验数据和标准模型理论值之间的偏差,而带电标量粒子则可以在较大的参数区域内使Higgs双光子衰变的理论预言值符合目前LHC上的实验数据. We introduce a new scalar triplet to produce masses for leptons, which is different from that for the quark sector in the standard model （SM）. The new neutral scalars can effectively decrease the deviation of the muon anomalous magnetic moment between the SM and the experimental measurements. The large ratio of Higgs to diphoton decay observed by LHC experiments, furthermore, can also be understood by the inclusion of the new physics enhancements induced by the new charged scalars.
