“…In the case neutrino electron scatterings, ν µ e − → ν µ e − and ν µ e − → ν µ e − , the contribution from (25) leads to a change of the g e L coupling: g e L → g e L + ξ. CHARM II experimental data on g L and g R [15] agree well with predictions of the Standard Model. Therefore ξ should be smaller than the experimental error ∆g e L : ξ < ∆g e L .…”

The Zee model predicts naturally two heavy, strongly degenerate and almost maximally mixed neutrinos and one light neutrino with small mixing. This pattern coincides with the one needed for a solution of the atmospheric neutrino problem by → oscillations and for existence of the two component hot dark matter in the Universe. Furthermore, the oscillations → e can be in the range of sensitivity of KARMEN, LSND experiments. The phenomenology of this scenario is considered and the possibility to check it in the forthcoming experiments is discussed. The scenario implies large values and inverse flavor hierarchy of couplings of the Zee boson with fermions: f e Ӷ f р f e ϳ0.1. The main signatures of the scenario are a strongly suppressed signal of → oscillation in CHORUS and NOMAD experiments, so that a positive result from these experiments will rule out the scenario, the possibility of the observation of e → oscillations by CHORUS and NOMAD, the corrections to the muon decay and neutrino-electron scattering at the level of experimental errors, and a branching ratio B(→e␥) bigger than 10 Ϫ13

“…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]. The background uncertainty is constrained to be σ β = 3% using the data with E vis θ 2 > 28 MeV, where the number of new physics events is negligible.…”

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.

The Born approximation, based onᾱ ≡ α(m Z ) instead of α, reproduces all electroweak precision measurements within their (1σ) accuracy. The low upper limits for the genuinely electroweak corrections constitute one of the major achievements of LEP. The astonishing smallness of these corrections results from the cancellation of a large positive contribution from the heavy top quark and large negative contributions from all other virtual particles. It is precisely the non-observation of electroweak radiative corrections that places stringent upper and lower limits on the top mass.
