On the Beta Function for Anisotropic Current Interactions in 2D
B. Gerganov, A. LeClair, M. Moriconi
By making use of current-algebra Ward identities we study renormalization of general anisotropic current-current interactions in 2D. We obtain a set of algebraic conditions that en…

Integrable Marginal Points in the N-Cosine Model
Bogomil Gerganov
The integrability of the N-cosine model, a N-field generalization of the sine-Gordon model, is investigated. We establish to first order in conformal perturbation theory that, for…

On the Integrability of the Bukhvostov-Lipatov Model
Marco Ameduri, Costas J. Efthimiou, Bogomil Gerganov
The integrability of the Bukhvostov-Lipatov four-fermion model is investigated. It is shown that the classical model possesses a current of Lorentz spin 3, conserved both in the bu…
