Description
The aim of this presentation is to introduce a dark extension of the SM that communicates to it through three portals: neutrino, vector and scalar mixing, by which it could be possible to explain the LEE at MiniBooNE. The model regards particularly the upscattering of HNLs (1 to N heavier Dirac or Majorana neutrinos) by the mediation of a dark photon, Z’, with masses around 10 MeV – 2 GeV, with the subsequent decay into an electron-positron pair that, if sufficiently collimated or asymmetric in energy, can be detected as a single shower event. Additionally, I present a fitting to the reconstructed neutrino energy. Two main cases are considered: 3 ν + 1 HNL (3+1) and 3 ν + 2 HNLs (3+2).
