Neutrino Excess and Dark Photons

Recently an excess of electron neutrino, $\nu_e$, events in a MiniBooNE experiment has been reported. An attempt to explain this anamoly was made in a theoretical analysis by introducing a new light Higgs Boson. In the present work we use a new neutrino interaction Z bosons producing Dark Photons to estimate an excess of $\nu_\mu \rightarrow \nu_e$ events.
