Abstract

The exact and explicit formulas for the quantum S-matrix elements of the soliton-antisoliton scattering which satisfy unitarity and crossing conditions and have correct analytical properties are constructed. This S-matrix is in agreement with the massive Thirring model perturbation theory and with the semiclassical sine-Gordon results.
