Free Field Representation For Massive Integrable Models
arXiv:hep-th/9307196 · doi:10.1007/BF02099357
Abstract
A new approach to massive integrable models is considered. It allows one to find symmetry algebras which define spaces of local operators and to get general integral representations for form-factors in the\ $ SU(2)$\ Thirring and Sine-Gordon models.
