Descripción
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.
