Superconformal affine Liouville theory

We present a superconformal invariant and integrable model based on the twisted affine Kac-Moody superalgebra osp(2vertical stroke2)(2), which is the supersymmetrization of the purely bosonic conformal affine Liouville theory recently proposed by Babelon and Bonora. Our model reduces to the super-Liouville or the super sinh-Gordon theories under certain limit conditions and can be obtained, via Hamiltonian reduction, from a superspace WZNW model with values in the corresponding affine Kac-Moody supergroup. The reconstruction formulae for classical solutions are given. The classical r-matrices in the homogeneous grading and the exchange algebras are worked out. (orig.)
