| Summary: | Abstract Dark photons coupling to $$L_\mu -L_\tau $$ L μ - L τ lepton number difference are a highly studied light dark matter candidate, with potential to be discovered through their impact on terrestrial neutrino oscillation experiments. We re-examine this in the light of claimed tensions between the NO $$\nu $$ ν A and T2K long baseline experiments, also taking into account data from the MINOS experiment. We obtain leading limits on the $$L_\mu -L_\tau $$ L μ - L τ gauge coupling $$g'$$ g ′ versus dark photon mass $$m_{A'}$$ m A ′ , improving upon previous bounds by up to a factor of five. We find no statistically significant alleviation of the tension from inclusion of the new physics effect. |
