Matrix model eigenvalue integrals and twist fields in thesu(2)-WZW model

Coulomb integrals for the SL ( 2 , R ) WZW model

We review the Coulomb gas computation of three point functions in the SL(2, R) WZW model and obtain explicit expressions for generic states. These amplitudes have been computed in the past by this and other methods but the analytic continuation in the number of screening charges required by the Coulomb gas had only been performed in particular cases. We show that the general ghost correlators c...

Φ Perturbations of WZW Model

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.

Parafermionic Reductions of WZW Model

We investigate a class of conformal Non-Abelian-Toda models representing a noncompact SL(2, R)/U(1) parafermionions (PF) interacting with a specific abelian Toda theories and having a global U(1) symmetry. A systematic derivation of the conserved currents, their algebras and the exact solution of these models is presented. An important property of this class of models is the affine SL(2, R)q al...
