Abstract
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 KL→ π0 + (invisible) events at the J-PARC KOTO experiment. We consider two models: i) Lμ− Lτ gauge boson with heavy vector-like quarks and ii) (Lμ− Lτ) + є(B3− Lτ ) 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.
