“…Agreement was found and the value sin 2 0 W = 0.29 + 0.05 was derived. This is consistent with the best value to date obtained by the CHARM II collaboration [80] in ν μ ε~ scattering, another purely leptonic process: sin 2 0 W = 0.239 + 0.011.…”

“…The fiducial volume in our analysis is confined to a transverse area of 320cm 2 , which corresponds to a fiducial mass of 547t, and the detection efficiency is taken to be 76%; efficiency for π 0 sample is quoted at 82% [84]. We reproduce the total number of ν −e scattering events with 3 GeV < E vis < 24 GeV, namely 2677 + 2752, to within a few percent level when setting the number of POTs in ν mode to be 1.69 of that in the ν mode [85]. We assume a flux uncertainty of σ α = 4.7% for neutrino, and σ α = 5.2% for antineutrino beam [84].…”

Heavy neutrinos with additional interactions have recently been proposed as an explanation to the MiniBooNE excess. These scenarios often rely on marginally boosted particles to explain the excess angular spectrum, thus predicting large rates at higher-energy neutrino-electron scattering experiments. We place new constraints on this class of models based on neutrino-electron scattering sideband measurements performed at MINERνA and CHARM-II. A simultaneous explanation of the angular and energy distributions of the MiniBooNE excess in terms of heavy neutrinos with light mediators is severely constrained by our analysis. In general, high-energy neutrino-electron scattering experiments provide strong constraints on explanations of the MiniBooNE observation involving light mediators.

“…In the right panel of figure 4, we show the expected number of such signal events as a function of the HNL mass for both the CHARM-II and FASERν2 experiments. Given the total observed number of ν andν electron scattering events in CHARM, which is equal to 2677 + 2752 [97], and using the relevant flux uncertainties of order 5% [98], we expect that a few hundred of additional JHEP05(2021)191 scattering events in CHARM from N e → N e processes would be a clear indication of the BSM effect. For the illustration purposes, we then assume that scenarios predicting N ev 500 such events are already excluded.…”

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.
