Non-zero Fermion Modes Contribution to the Instanton-Induced Electroweak Processes at High Energies
Abstract
We consider instanton-induced high energy processes in an electroweak-type model. Multi-fermion final states are taken into account in Gauss approximation. Unlike previous results we calculate nonzero fermion modes contribution to cross-section by straightforward procedure. This contribution can be important at energies of sphaleron mass order.
