NSI to solve the KOTO anomaly

This article in 2008, shows an attempted to resolve the KOTO and Invisible beutry decay anomalies via a new neutrino interaction, (there U(1) B-L) https://arxiv.org/abs/2008.09793

Differences between Nova and T2K experiment hint (1.8 sigma) at a Neutrino Firth Force

https://arxiv.org/pdf/2409.10599 states the current status on a NSI is ~1.8 sigma and it is due to a CP violating phase Tension in measurements. With the axial force C is violated in matter neutrino interactions, due to matter being matter and not anti-matter, P and perhaps CP might be violated if the matter has a net axial charge where the neutrinos where passing.
