Higher orders of perturbation theory in the neighborhood of a classical solution

V. B. Tverskoi


Abstract: Higher quantum perturbation theory orders in classical background are considered on the basis of the approach suggested in the previous paper. Expressions for the operator-valued field arguments are obtained and with the help of semiclassical LSZ-procedure, the scattering of a soliton and secondary field quanta is investigated. In terms of asymptotic fields an expression for the mass operator is obtained for which a precise physical interpretation is pointed out.
