Form factors of exponential fields for two-parametric family of integrable models

摘要: Abstract A two-parametric family of integrable models (the SS model) that contains as particular cases several well known quantum field theories is considered. After the group restriction it describes a wide class perturbed conformal theories. Exponential fields in model are closely related to primary these We use bosonization approach derive an integral representation for form factors exponential model. The same representations sausage and cosine–cosine obtained limiting cases. results tested at special points, where theory free particles.
