Algebraic approach to form factors in the complex sinhGordon theory
Abstract
We study form factors of the quantum complex sinhGordon theory in the algebraic approach. In the case of exponential fields the form factors can be obtained from the known form factors of the Z_{N}symmetric Ising model. The algebraic construction also provides an Ansatz for form factors of descendant operators. We obtain generating functions of such form factors and establish their main properties: the cluster factorization and reflection equations.
