Correlation Functions in 2-Dimensional Integrable Quantum Field Theories
Abstract
Description
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 $T_{μν}(x)$ of the theory.
