Quantum fluctuations in the vicinity of an instanton in the SU(N) group
Description
A general form of the quadratic Lagrangian in the presence of a self-dual classical field has been obtained. The calculation of the amplitude of the vacuum-vacuum transition in the SU(N) group has been reduced to calculation of similar amplitudes in the SU(2) group for scalar particles with different isospins. The value of the amplitude for one instanton has been obtained. (Auth.)
