چکیده
The two-photon two-neutrino interaction induced by magnetic field is investigated. In particular the processes γγ → ν ¯ ν and γ → γν ¯ ν are studied in the presence of strong magnetic field. An effective La-grangian and partial amplitudes of the processes are presented. Neu-trino emissivities due to the reactions γγ → ν ¯ ν and γ → γν ¯ ν are calculated taking into account of the photon dispersion and large ra-diative corrections. A comparison of the results obtained with previous estimations and another inducing mechanisms of the processes under consideration is made.

We discuss the interaction of photons with neutrinos including two lepton loops. The parity violation in the γν → γν channel due to two lepton loops is substantially enhanced relative to the one lepton loop contribution. However there is no corresponding enhancement in the parity conserving amplitude in either the direct or the cross channel γγ → ν ¯ ν.

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.

A remarkable number of studies have been performed at LEP in the field of two-photon physics in the last four years. These results represent a very important contribution to the understanding of strong interactions at low energies. In particular, significant deviations from QCD predictions are found in the cross sections of inclusive single particle, jet and beauty production. A concise review ...

The KamLAND reactor antineutrino experiment has detected a 3.4σ flux suppression relative to the expectation if no neutrino oscillations occur. We combine Kam-LAND data with solar neutrino data and show that the LMA solution is the only viable oscillation solution to the solar neutrino problem at the 4.4σ C. L.
