“…In this study, instead, we will focus on BSM scenarios predicting neutrino upscatterings into BSM heavy neutral leptons (HNLs) that are mediated by light vector particles or photons in the dipole portal model (see, e.g., refs. [24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40] for further discussion about the models and their phenomenology). As we show, in such scenarios the BSM neutrino scatterings can lead to new types of signatures in the FASER and FASERν detectors.…”

The neutrino physics program at the LHC, which will soon be initiated by the FASER experiment, will provide unique opportunities for precision studies of neutrino interaction vertices at high energies. This will also open up the possibility to search for beyond the standard model (BSM) particles produced in such interactions in the specific high-energy neutrino beam-dump experiment. In this study, we illustrate the prospects for such searches in models with the dipole or Z′ portal to GeV-scale heavy neutral leptons. To this end, we employ both the standard signature of new physics that consists of a pair of oppositely-charged tracks appearing in the decay vessel, and the additional types of searches. These include high-energy photons and single scattered electrons. We show that such a variety of experimental signatures could significantly extend the sensitivity reach of the future multi-purpose FASER 2 detector during the High-Luminosity phase of the LHC.

“…Atmospheric and solar neutrinos. The magnetic moment operator (3) can lead to the up-scattering of atmospheric or solar neutrinos to the heavy neutrino, which can give observable signals in IceCube [24] or dark matter detectors [25], respectively. The latter can test heavy neutrinos with mass below ∼ 10 MeV.…”

Explaining the MiniBooNE excess by a decaying sterile neutrino with mass in the 250 MeV range

2020

The MiniBooNE collaboration has reported an excess of 460.5 ± 95.8 electron-like events (4.8σ). We propose an explanation of these events in terms of a sterile neutrino decaying into a photon and a light neutrino. The sterile neutrino has a mass around 250 MeV and it is produced from kaon decays in the proton beam target via mixing with the muon or the electron in the range 10 −11 |U 4 | 2 10 −7 ( = e, µ). The model can be tested by considering the time distribution of the events in MiniBooNE and by looking for single-photon events in running or upcoming neutrino experiments, in particular by the suite of liquid argon detectors in the short-baseline neutrino program at Fermilab.

“…We will show that inelastic scattering of sterile neutrino DM from Xenon electrons is able to successfully reconstruct the XENON1T event rate. The interaction of sterile neutrinos with electrons for explaining the XENON1T excess has been recently studied in [66,67], where an incoming flux of solar neutrinos up scatters to an outgoing state of sterile neutrinos. In contrast to the case of incoming sterile neutrinos, their results do not rely on the nature of sterile neutrinos as DM particles.…”

The XENON1T collaboration recently reported the excess of events from recoil electrons, possibly giving an insight into new area beyond the Standard Model (SM) of particle physics. We try to explain this excess by considering effective interactions between the sterile neutrinos and the SM particles. In this paper, we present an effective model based on one-particle-irreducible interaction vertices at low energies that are induced from the SM gauge symmetric four-fermion operators at high energies. The effective interaction strength is constrained by the SM precision measurements, astrophysical and cosmological observations. We introduce a novel effective electromagnetic interaction between sterile neutrinos and SM neutrinos, which can successfully explain the XENON1T event rate through inelastic scattering of the sterile neutrino dark matter from Xenon electrons. We find that sterile neutrinos with masses around 90 keV and specific effective coupling can fit well with the XENON1T data where the best fit points preserving DM constraints and possibly describe the anomalies in other experiments.
