Exact form factors of the SU(N) Gross-Neveu model and 1/N expansion
Hrachya Babujian, Angela Foerster, Michael Karowski
The general SU(N) form factor formula is constructed. Exact form factors for the field, the energy momentum and the current operators are derived and compared with the 1/N-expansio…
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…
Towards the Construction of Wightman Functions of Integrable Quantum Field Theories
H. Babujian, M. Karowski
The purpose of the ``bootstrap program'' for integrable quantum field theories in 1+1 dimensions is to construct a model in terms of its Wightman functions explicitly. In this arti…
The Form Factors and Quantum Equation of Motion in the sine-Gordon Model
H. Babujian, M. Karowski
Using the methods of the 'form factor program' exact expressions of all matrix elements are obtained for several operators of the quantum sine-Gordon model alias the massive Thirri…
