Motivated by the evidence for a finite neutrino mass we examine anew the interaction of neutrinos in a magnetic field. We present the rate for radiative scattering for both massless and massive neutrinos in the standard model and give the corresponding numerical estimates. We also consider the effects arising from a possible neutrino magnetic moment.

The problem of neutral-current processes (neutrino scattering, pair emission, pair absorption, axion emission, etc.) in a nuclear medium can be separated into an expression representing the phase space of the weakly interacting probe, and a set of dynamic structure functions of the medium. For a non-relativistic medium we reduce the description to two structure functions SA(ω) and SV (ω) of the...

We present calculations of the magnetic moment contribution to neutrino electron scattering in large extra dimension brane-bulk models (LED) with three bulk neutrinos. We discuss the cases with two and three large extra dimensions of sizes R. The calculations are done using reactor flux from Uranium, 235U as the neutrino source. We find that if the electron neutrino mass is chosen to be in the ...

In proto-neutron stars with strong magnetic fields, the neutrino-nucleon scattering/absorption cross sections depend asymmetrically on the direction of neutrino momentum with respect to the magnetic field axis, a manifestation of parity violation in weak interactions. We develop the moment formalism of neutrino transport in the presence of such asymmetric neutrino opacities. For a given neutrin...

Contributions to inelastic scattering arising from the interference of a weak neutral current with the electromagnetic current are calculated using the Weinberg model and the quark parton model. These interferences produce nonvanishing (dd daf) , -(L) (do d$(R)), (dostL) do-(R)) which give rise to sizeable affects when compared to the purely electromagnetic scattering. (Submitted to Phys. Rev. ...
