Unitarity Restrictions on Semi-Classical Approximations to Certain Functional Integrals

摘要

Estimates of physically relevant quantities (cross sections, multiplicities, correlations) in eikonal models of high-energy field theories lead to a class of semiclassical solutions to nonlinear Euler equations. The requirement of unitarity restricts these possible solutions to a unique function of energy and impact parameter. (ERA citation 04:020780)
