Testing Meson Portal Dark Sector Solutions to the MiniBooNE Anomaly at CCM Open
A solution to the MiniBooNE excess invoking rare three-body decays of the charged pions and kaons to new states in the MeV mass scale was recently proposed as a dark-sector explanation. This class of solution illuminates the fact that, whi…
