New physics implications of recent search for $K_L \to \pi^0 \nu\bar{\nu}$ at KOTO

The KOTO experiment recently reported four candidate events in the signal region of KL→π0νν¯ search, where the standard model only expects 0.10±0.02 events. If confirmed, this requires physics beyond the standard model to enhance the signal. We examine various new physics interpretations of the resu...
