Abstract

Description

The form factor equations are solved for an SU(N) invariant S-matrix under the assumption that the anti-particle is identified with the bound state of N-1 particles. The solution is obtained explicitly in terms of the nested off-shell Bethe ansatz where the contribution from each level is written in terms of multiple contour integrals.
This work is dedicated to the 75th anniversary of H. Bethe's foundational work on the Heisenberg chain
