- Is it allowed by conservation laws?
- If so, what is the cross-section of interaction?
Neutrino cross-sections for electromagnetic interactions are vanishingly small. The stopping length of a neutrino in solid lead is about a lightyear.
Photon-photon scattering is hugely more probable, and that never happens, either.
