Correlation Functions in 2-Dimensional Integrable Quantum Field Theories
G. Mussardo
Abstract
In this talk I discuss the form factor approach used to compute correlation functions of integrable models in two dimensions. The Sinh-Gordon model is our basic example. Using Watson's and the recursive equations satisfied by matrix elements of local operators, I present the computation of the form factors of the elementary field ϕ(x) and the stress-energy tensor Tμν(x) of the theory.
