Exact form factors in integrable quantum field theories: the sine-Gordon model (II)
H. Babujian, M. Karowski
A general model independent approach using the `off-shell Bethe Ansatz' is presented to obtain an integral representation of generalized form factors. The general techniques are ap…

The Form Factors and Quantum Equation of Motion in the sine-Gordon Model
H. Babujian, M. Karowski
Using the methods of the 'form factor program' exact expressions of all matrix elements are obtained for several operators of the quantum sine-Gordon model alias the massive Thirri…
