Form factors of SU(N) invariant Thirring model

چکیده
We obtain a new integral formula for solutions of the rational quantum Knizhnik-Zamolodchikov equation associated with Lie algebra slN at level zero. Our formula contains the integral representation of form factors of SU(N) invariant Thirring model constructed by F. Smirnov. We write down recurrence relations arising from the construction of the form factors. We check that the recurrence relations hold for the form factors of the energy momentum tensor.

On Form Factors of SU(2) Invariant Thirring Model
Integral formulae for form factors of a large family of charged local operators in SU(2) invariant Thirring model are given extending Smirnov’s construction of form factors of chargeless local operators in the sine-Gordon model. New abelian symmetry acting on this family of local operators is found. It creates Lukyanov’s operators which are not in the above family of local operators in general.
متن کاملThirring model with boundary reflection
We study the SU(n) invariant massive Thirring model with boundary reflection. Our approach is based on the free field approach. We construct the free field realizations of the boundary state and it’s dual. For an application of these realizations, we present integral representations for the form factors of the local operators.
متن کاملThe Chiral Space of Local Operators in SU(2)-Invariant Thirring Model
The space of local operators in the SU(2) invariant Thirring model (SU(2) ITM) is studied by the form factor bootstrap method. By constructing sets of form factors explicitly we define a susbspace of operators which has the same character as the level one integrable highest weight representation of ŝl2. This makes a correspondence between this subspace and the chiral space of local operators in...
متن کاملToda fields with boundary reflection
We study the affine A (1) n−1 Toda fields with boundary reflection. Our approach is based on the free field approach. We construct free field realizations of the boundary state and its dual. For an application of these realizations, we present integral representations for the form factors of the local operators. In a limiting case ρ → ∞, our integral representations reproduce those of form fact...
