Non-standard neutrino-nucleon interaction is formulated and explored within the energy range of quasi-elastic scattering. In particular, the study focuses on the neutral-current elastic (anti)neutrino scattering off nucleons described by the exotic reactions να(να) + n → ν β (ν β ) + n and να(να) + p → ν β (ν β ) + p, which provide corrections to the dominant Standard Model processes. In this context, it is shown that the required exotic nucleon form factors may have a significant impact on the relevant cross sections. Besides cross sections, the event rate is expected to be rather sensitive to the magnitude of the lepton-flavour violating parameters resulting in an excess of events. The overlap of non-standard interactions and strange quark contributions, in the region of few GeV neutrino energies, is also examined. The formalism is applied for the case of the relevant neutrino-nucleon scattering experiments (LSND, MiniBooNE, etc.) and motivates the notion that such facilities have high potential to probe NSI. * dimpap@cc.uoi.gr † hkosmas@uoi.gr

Recently hints of lepton flavor non-universality emerged in the BaBar and LHCb experiments. In this paper we propose tests of lepton universality in ν τ scattering. To parametrize the new physics we adopt an effective Lagrangian approach and consider the neutrino deep inelastic scattering processes ν τ + N → τ + X and ν µ + N → µ + X where we assume the largest new physics effects are in the τ sector. We also consider an explicit leptoquark model in our calculations. In order to make comparison with the standard model and also in order to cancel out the uncertainties of the parton distribution functions, we consider the ratio of total and differential cross sections of tau-neutrino to muon-neutrino scattering. We find new physics effects that can possibly be observed at the proposed Search for Hidden Particles (SHiP) experiment at CERN.

“…Constraints on the new couplings come from the hadronic τ decays. We will consider constraints from the decays τ − → π − ν τ and τ − → ρ − ν τ [4,5]. There are several reasons to consider NSI involving the (ν τ , τ ) sector.…”

We discuss the impact of the presence of a charged Higgs and a W ′ gauge boson on the tau-neutrino nucleon scattering ν τ + N → τ − + X and ν τ + N → τ + + X. We show the effect of the new physics on the three subprocesses quasielastic, ∆-resonance, and deep inelastic scattering. The measurement of the atmospheric and reactor mixing angles θ 23 and θ 13 , respectively, relies on the standard model cross section of the above processes if they have been measured in the appearance channels ν µ → ν τ and ν e → ν τ (ν e → ν τ ), respectively. Consideration of the new physics contributions to those reactions modifies the measured mixing angles, assuming the standard model cross section. We include form factor effects in the new physics calculations and find the deviations of the mixing angles which can be significant and can depend on the energy of the neutrino.PRESENTED AT DPF
