On the soliton spectrum of field theories with character interactions
Abstract
It is shown that a soliton ansatz in field theories where the interaction is determined by the characters of compact Lie groups can be reduced to the sine-Gordon equation with higher harmonics. The mass spectrum of the basic solitons and the one-loop quantum corrections to it are found for characters of adjoint representations of compact Lie groups with nontrivial center.
