Leading power corrections to the semiclassical approximation for gauge meson collisions in the oneinstanton sector
Abstract
The leading quantum corrections for the 2 → n process involving vector particles in QCD and in the electroweak theory are calculated in the oneinstanton sector. That is, all corrections of the form ( αp^{2}s) ^{N} are calculated for a fixed N as s→ ∞. The Nth quantum correction is found to be part of an exponential series though it seems difficult to take N large enough to apply the result in the most interesting cases.
