Neutrino Excess and Dark Photons

TL;DR

This paper investigates whether dark photons produced via Z boson interactions can explain the observed electron neutrino excess in MiniBooNE, proposing a new physics mechanism involving neutrino interactions.

Contribution

It introduces a novel approach using dark photon production through Z bosons to account for neutrino excess, expanding beyond previous explanations involving light Higgs bosons.

Findings

Dark photon production can produce an excess of $ u_$ events.

The model provides a potential explanation for MiniBooNE anomaly.

Results suggest new physics involving dark photons may be relevant.

Abstract

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.
