Direct computation of inelastic photon-neutrino processes in the Standard Model

In this paper, we compute the Standard Model polarized amplitudes and cross sections of the processes $\gamma\nu\to\gamma\gamma \nu$, $\gamma\gamma \to energies $ømega$ within the range of validity of the Fermi theory. By using a large electron-mass expansion of the exact result, we also derive the...

description In this paper, we compute the Standard Model polarized amplitudes and cross sections of the processes $\gamma\nu\to\gamma\gamma \nu$, $\gamma\gamma \to energies $ømega$ within the range of validity of the Fermi theory. By using a large electron-mass expansion of the exact result, we also derive the first correction term to the effective, low-energy ($ømega < m_e$) formula for implications of our results and provide simple fits to the exact expressions.
