摘要: A general model independent approach using the `off-shell Bethe Ansatz' is presented to obtain an integral representation of generalized form factors. The techniques are applied quantum sine-Gordon alias massive Thirring model. Exact expressions all matrix elements obtained for several local operators. In particular soliton factors charge-less operators as example higher currents investigated. It turns out that various correspond specific scalar functions called p-functions. identification performed. exact results checked with Feynman graph expansion and full agreement found. Furthermore eigenvalues infinitely many conserved charges calculated agree what expected from classical case. Within frame work integrable field theories a `crossing' formula derived. `bound state intertwiners' introduced bound again integrations performed in lowest breathers simple obtained.
