论文摘要
我们讨论了$（g-2）_ $中长期实验性异常的可能的轻量规玻色子解释，以及$ k_l \ rightarrowπ^0 + \ text {（Invisible）} $事件的$（g-2）_ $的近期异常过剩。我们考虑两种型号：$ i $）$l_μ-l_τ$仪表玻色子，带有重型矢量夸克和$ ii $）$（l_μ-l_τ） +ε（b_3-l_3-l_τ）$ gauge boson在右手中子的情况下。当灯光玻色子的质量接近中性锥子以满足Grossman-Nir结合时，这些模型成功地同时解释了异常，同时满足了所有已知的实验约束。我们广泛提供建议模型的未来前景。
We discuss a list of possible light gauge boson interpretations for the long-standing experimental anomaly in $(g-2)_μ$ and also recent anomalous excess in $K_L \rightarrow π^0 + \text{(invisible)}$ events at the J-PARC KOTO experiment. We consider two models: $i$) $L_μ- L_τ$ gauge boson with heavy vector-like quarks and $ii$) $(L_μ- L_τ) + ε(B_3 - L_τ)$ gauge boson in the presence of right-handed neutrinos. When the light gauge boson has mass close to the neutral pion in order to satisfy the Grossman-Nir bound, the models successfully explain the anomalies simultaneously while satisfying all known experimental constraints. We extensively provide the future prospect of suggested models.
