dc.description.abstract
We apply previous results on the O (N) Bethe Ansatz [1-3] to construct a
general form factor formula for the O (N) Gross-Neveu model. We examine this
formula for several operators, such as the energy momentum, the spin-field and
the current. We also compare these results with the 1/N expansion of this
model and obtain full agreement. We discuss bound state form factors, in
particular for the three particle form factor of the field. In addition for
the two particle case we prove a recursion relation for the K-functions of the
higher level Bethe Ansatz.
