论文摘要
中微子磁偶极力矩在SM的简单扩展中进行了研究，该SM用量子数$（\ bar {\ BoldSymbol {3}}，\ boldsymbol {1}，1/3）$的标量leptokark增强。为了达到相当的中微子磁矩，我们在框架中包括了右手中微子的贡献和对标量LQ的一环贡献的分析结果。允许的参数空间是通过对MUON $（G-2）$，$τ\ toμγ$和$ B_C \ toτ^ - \τ^ - \barν$衰减的最新限制找到的。结果表明，存在参数空间的一个区域，可以容纳XENON协作最近报告的异常。
The neutrino magnetic dipole moment is studied in a simple extension of the SM augmented with a scalar Leptoquark with quantum numbers $(\bar{\boldsymbol{3}},\boldsymbol{1},1/3)$. In order to reach a sizeable neutrino magnetic moment, we include in the framework the contribution of right-handed neutrinos and analytical result for the one-loop contribution of a scalar LQ is presented. The allowed parameter space is found through recent restrictions on the muon $(g-2)$, the $τ\to μγ$ and the $B_c \to τ^- \bar ν$ decay. It is shown that exist a region of the parameter space where the recent anomaly reported by the XENON collaboration can be accommodated.
