SUMMARY
The discussion centers on the first-order Feynman diagrams relevant to the neutrino-antineutrino scattering reaction, specifically neutrino + antineutrino → W(+) + W(-). Participants confirm that at tree level, there is primarily one diagram in the crossed channel: νe + W- → e- → νe + W-. Additionally, a participant raises the question of whether an s-channel Z boson contributes to the process, indicating a need for further exploration of this aspect.
