Low-energy neutrino-photon inelastic interactions
Abstract
Description
The computation of the polarized amplitudes and cross section of the processes $γν\toγγν$, $γγ\to γν\barν$ and $ν\barν\to γγγ$ is described. We used an effective lagrangian approach for energies below the threshold for $e^+e^-$ pair production and the complete computation at higher energies for application in supernova dynamics. Leading contributions of physics beyond the SM are also commented.
