Abstract

The leading contribution of the gauge propagator to the inclusive baryon-number-violating cross-section in electroweak theory is calculated using the Levine–Yaffe propagator in the instanton background. The result resolves a current discrepancy between two calculational approaches to high energy baryon number violation, the "valley method" and the "R-term method".
