Extending the Reach of Leptophilic Boson Searches at DUNE and MiniBooNE with Bremsstrahlung and Resonant Production

Abstract

New gauge bosons coupling to leptons are simple and well-motivated extensions of the Standard Model. We study the sensitivity to gauged $L_{\mu }-L_e$, $L_e-L_{\tau }$ and $L_{\mu }-L_{\tau }$ both with the existing beam dump mode data of MiniBooNE and with the DUNE near detector. We find that including bremsstrahlung and resonant production of $Z^{\prime }$ which decays to $e^{\pm }$ and ${\mu }^{\pm }$ final states leads to a significant improvement in existing bounds, especially for $L_{\mu }-L_e$ and $L_e-L_{\tau }$ for DUNE while competitive constraints can be achieved with the existing data from the MiniBooNE's beam dump run.
