The extraction of neutrino mixing parameters from accelerator-based oscillation experiments relies on proper modeling neutrino-nucleus scattering processes using neutrino-interaction event generators. Experimental tests these generators are difficult due to the broad range energies produced in beams and low statistics current experiments. Here we overcome difficulties by exploiting similarity e...

During the process of thermal leptogenesis temperature decreases by about one order of magnitude while the baryon asymmetry is generated. We present an analytical description of this process so that the dependence on the neutrino mass parameters becomes transparent. In the case of maximal CP asymmetry all decay and scattering rates in the plasma are determined by the mass M1 of the decaying hea...

New results from the CCFR Collaboration on the structure functions F2 and xF3 are presented. Neutrino scattering structure function measurements o er a unique tool to probe the strong interactions. The parity-violating structure function xF3(x;Q ) can only be measured in deep inelastic neutrino scattering. Precise measurements of the structure function F2(x;Q ) can also be obtained. The predict...

We are reporting on a determination of neutral current coupling constants from a study of differential cross sections of muon(anti)neutrino-electron scattering. The results were obtained with the CHARM-II detector which was exposed to the CERN wide band neutrino beam in the years 1987-1990. A total of about 2100 ve and 2200 ve scattering events were observed. From a comparison between the data ...

The energy spectrum of recoil electrons from solar neutrino scattering, as observed by Superkamiokande, is deformed with respect to that expected from SSM calculations. We considered ν − e scattering from neutrinos produced by the electron–capture on 8B nuclei, e +8 B →8 Be + νe, as a possible explanation of the spectral deformation. A flux ΦeB ≃ 10 4 cm−2 s−1 could account for Superkamiokande ...

A novel method to look for neutrino oscillations is proposed based on the elastic scattering process ν̄ie − → ν̄ie−, taking advantage of the dynamical zero present in the differential cross section for ν̄ee − → ν̄ee−. An effective tunable experiment between the ”appearance” and ”disappearance” limits is made possible. Prospects to exclude the allowed region for atmospheric neutrino oscillations are...

The possibility to determine the axial strange form factor of the nucleon from elastic neutrino-nucleon scattering experiments is studied. The existing experimental information is shortly mentioned and several observables which could be measured in the near future at new neutrino facilities are discussed.

We investigate the potential of near–future neutrino telescopes like NESTOR for searches for exotic processes in ultrahigh energy neutrino–quark scattering. We consider signatures such as muon bundles and/or contained cascades from the nonperturbative production of multiple weak gauge bosons in the Standard Model, compositeness and leptoquark production.

We present a new measurement of the difference between the nucleon strange and antistrange quark distributions from dimuon events recorded by the NuTeV experiment at Fermilab. This analysis is the first to use a complete next to leading order QCD description of charm production from neutrino scattering. Dimuon events in neutrino deep inelastic scattering allow direct and independent study of th...

Radiative corrections to the electron recoil-energy spectra and to total cross sections are computed for neutrino-electron scattering by solar neutrinos. Radiative corrections change monotonically the electron recoil spectrum for incident 8 B neutrinos, with the relative probability of observing recoil electrons being reduced by about 4 % at the highest electron energies. For p p and 7 Be neutr...
