For neutrino scattering from polarized electron, the weak interaction term in the cross section is significantly suppressed by the polarized term. The magnetic moment term does not receive any correction from the electron polarization. Hence, the study of the magnetic moment of neutrinos through scattering from the polarized electron leads to a stronger bound on the neutrino magnetic moment com...

Recent progress in neutrino scattering experiments with few GeV neutrino beams is reviewed, focusing on new experimental input since the beginning of the NuInt workshop series in 2001. Progress in neutrino quasi-elastic scattering, resonance production, coherent pion production, scattering in the transition region between the resonance and deep inelastic regimes, and nuclear effects in neutrino...

Precision tests of the standard model are essential for constraining models of new physics. Neutrino–electron elastic scattering offers a clean probe into many electroweak effects that are complimentary to the more canonical measurements done at collider facilities. Such reactions are rare, even as compared with the already tiny cross-sections for neutrino–nucleon scattering, and competitive pr...

Large flux uncertainties and small cross sections have made neutrino scattering physics a challenge. However, a worthwhile challenge, as these tiny particle interactions can teach us a lot about neutrinos themselves, the weak interaction, and nucleon structure. As well, knowledge of these cross sections is crucial input to the growing field of neutrino oscillation physics. New, intense, well un...

The neutrino-nucleon scattering in a collapsing star envelope with a strong magnetic field is investigated. The transferred by neutrinos momentum asymmetry along the field direction is obtained. It is shown that the neutrino-nucleon scattering gives a contribution to the asymmetry comparable with direct URCA processes. Hence, the neutrino-nucleon scattering should be taken into account in estim...

We construct the open-string scattering amplitudes for neutrino-gluon collisions and evaluate the high energy neutrino-nucleon scattering cross section via string state excitations in the TeV string-scale scenario. We find that the neutrino-gluon scattering is the dominant contribution, 5 − 10 times larger than neutrino-quark processes, though black hole production may be larger than the string...

Neutrino scattering physics is discussed for investigating internal structure of the nucleon and nuclei at future neutrino facilities. We explain structure functions in neutrino scattering. In particular, there are new polarized functions g3, g4, and g5, and they should provide us important information for determining internal nucleon spin structure. Next, nuclear structure functions are discus...

Knowledge of neutrino interactions with a nuclear target at the neutrino energy around sub-GeV is recently getting more and more important as necessary information for accelerator based neutrino oscillation experiments. A study of neutrino interactions contains rich physics of neutrinos with nucleus, and is used to reveal the properties of neutrinos in the oscillation measurements. We review th...

We present a model for inclusive electron and neutrino scattering off nuclei paying special attention to the influence of in-medium effects on the quasielastic scattering and pion-production mechanisms. Our results for electron scattering off 16O are compared to experimental data at beam energies ranging from 0.7 to 1.5 GeV. The good description of electron scattering serves as a benchmark for ...
