Φ(2) Perturbations of WZW Model
Vadim A. Brazhnikov
Abstract
We study su(2)k WZW model perturbed by a multiplet of primary fields. The theory has a rich variety of particles. Presence of nontrivial decay processes is a peculiarity of the model. We prove integrability by explicit construction of quantum conserved currents. The scattering theory is briefly discussed.
