Abstract:
The purpose of the "bootstrap program" for integrable quantum field theories
in 1+1 dimensions is to construct a model explicitly in terms of its
Wightman functions. We illustrate this program here mainly in terms of
the SU(N) Gross–Neveu model. We construct the nested off-shell Bethe ansatz
for an SU(N) factoring S-matrix and consider the problem of how to sum
over intermediate states in the short-distance limit of the two-point
Wightman function for the sinh-Gordon model.
Keywords:
integrable quantum field theory, form factor.
