Description
New gauge bosons coupling to leptons are simple and well-motivated extensions of the StandardModel. 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 toe±andμ±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.
