On the Form Factors of Relevant Operators and their Cluster Property
C. Acerbi, G. Mussardo, A. Valleriani
We compute the Form Factors of the relevant scaling operators in a class of integrable models without internal symmetries by exploiting their cluster properties. Their identificati…

Non-integrable Quantum Field Theories as Perturbations of Certain Integrable Models
G. Delfino, G. Mussardo, P. Simonetti
We approach the study of non--integrable models of two--dimensional quantum field theory as perturbations of the integrable ones. By exploiting the knowledge of the exact -matri…
