High energy e- e- scattering, ratio inelastic/elastic cross-sections?

Click For Summary
SUMMARY

The discussion centers on estimating the ratio of inelastic to elastic cross-sections in high-energy electron-electron scattering, specifically when the energy is significantly greater than the electron mass (E >> m_e). Participants explore the dominant inelastic collision mechanism, which involves the emission of a single photon during the interaction. The conversation highlights the importance of understanding electron-electron interactions in high-energy physics.

If we were to scatter high energy (say E>>m_e) electrons off each other is there a hand wavy argument to come up with a rough estimate for the ratio of inelastic to elastic cross-sections?

Would the dominate inelastic collision between two high energy electrons result in a single photon emitted?

Thanks for any help!
