Title:
Exact Form Factors in Integrable Quantum Field Theories
Speaker:
Abstract:
The purpose of the bootstrap program for integrable quantum field theories in 1+1 dimension is the explicit solution of the model in terms of its Wightman functions. This program classifies integrable quantum field theoretic models also. By use of "off-shell Bethe Ansatz" technique we construct an integral representation of form factors of the model. We demonstrate the technique in several simple examples and present recent results on O(N) Gross-Neveu model.
