The nested SU(N) off-shell Bethe ansatz and exact form factors
Hratchia M. Babujian, Angela Foerster, Michael Karowski
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 i…
The Form Factor Program: a Review and New Results - the Nested SU(N) Off-Shell Bethe Ansatz
Hratchya M. Babujian, Angela Foerster, Michael Karowski
The purpose of the ''bootstrap program'' for integrable quantum field theories in 1+1 dimensions is to construct explicitly a model in terms of its Wightman functions. In this arti…
Exact form factors in integrable quantum field theories: the scaling Z(N)-Ising model
H. Babujian, A. Foerster, M. Karowski
A general form factor formula for the scaling Z(N)-Ising model is constructed. Exact expressions for matrix elements are obtained for several local operators. In addition, the comm…
