S-matrices and bi-linear sum rules of conserved charges in affine Toda field theories
نویسنده
چکیده
The exact quantum S-matrices and conserved charges are known for affine Toda field theories(ATFTs). In this note we report on a new type of bi-linear sum rules of conserved quantities derived from these exact S matrices. They exist when there is a multiplicative identity among S-matrices of a particular ATFT. Our results are valid for simply laced as well as non-simply laced ATFTs. We also present a few explicit examples. PACS: 11.10.Kk; 11.55.Ds; 02.20.Tw

Exact S-matrices with Affine Quantum Group Symmetry
We show how to construct the exact factorized S-matrices of 1+1 dimensional quantum field theories whose symmetry charges generate a quantum affine algebra. Quantum affine Toda theories are examples of such theories. We take into account that the Lorentz spins of the symmetry charges determine the gradation of the quantum affine algebras. This gives the S-matrices a non-rigid pole structure. It...
متن کاملConserved charges and soliton solutions in affine Toda theory
We study the conserved charges of affine Toda field theories by making use of the conformally invariant extension of these theories. We compute the values of all charges for the single soliton solutions, and show that these are related to eigenvectors of the Cartan matrix of the finite-dimensional Lie algebra underlying the theory.
متن کاملThe Quantum Spectrum of the Conserved Charges in Affine Toda Theories
The exact eigenvalues of the infinite set of conserved charges on the multiparticle states in affine Toda theories are determined. This is done by constructing a free field realization of the Zamolodchikov-Faddeev algebra in which the conserved charges are realized as derivative operators. The resulting eigenvalues are renormalization group (RG) invariant, have the correct classical limit and p...
متن کاملS-Matrix Identities in Affine Toda Field Theories
We note that S-matrix/conserved charge identities in affine Toda field theories of the type recently noted by Khastgir can be put on a more systematic footing. This makes use of a result first found by Ravanini, Tateo and Valleriani for theories based on the simply-laced Lie algebras (A, D and E) which we extend to the nonsimply-laced case. We also present the generalisation to nonsimply-laced ...
متن کاملQuantum Conserved Currents in Affine Toda Theories
We study the renormalization and conservation at the quantum level of higher-spin currents in affine Toda theories with particular emphasis on the nonsimply-laced cases. For specific examples, namely the spin-3 current for the a (2) 3 and c (1) 2 theories, we prove conservation to all-loop order, thus establishing the existence of factorized S-matrices. For these theories, as well as the simply...
