Abstract

We comment on introduction of the instanton collective coordinates in the theories with the spontaneously broken gauge symmetry. In distinction with the pure gauge theories some gauge-invariant quantities acquire explicit dependence on the collective coordinates associated with the gauge field orientation in the gauge group, which looks rather paradoxically. This dependence, however, is absolutely necessary for preserving the Lorentz invariance of the instanton-induced amplitudes.
