Determination of Fusion Rule for E7-Type Conformal Field Theory
نویسندگان
چکیده
We show that the fusion rule for a modular invariant Ertype conformal field theory, which is constructed from the one for the A,(l) Kac-Moody algebra by naive extension, is not associative. Then by imposing .further restrictions to this naive fusion rule, we obtain associative fusion rules for the E7-type conformal field theory. Unlike the case of an E6-type conformal field theory, these fusion rules cannot be factorized into left and right sectors.

Fusion Rules in Conformal Field Theory
Several aspects of fusion rings and fusion rule algebras, and of their manifestations in two-dimensional (conformal) field theory, are described: diagonalization and the connection with modular invariance; the presentation in terms of quotients of polynomial rings; fusion graphs; various strategies that allow for a partial classification; and the role of the fusion rules in the conformal bootst...
متن کاملPerturbed Defects and T-Systems in Conformal Field Theory
Defect lines in conformal field theory can be perturbed by chiral defect fields. If the unperturbed defects satisfy su(2)-type fusion rules, the operators associated to the perturbed defects are shown to obey functional relations known from the study of integrable models as T-systems. The procedure is illustrated for Virasoro minimal models and for Liouville theory. Email: [email protected]
متن کاملD-brane Conformal Field Theory
We outline the structure of boundary conditions in conformal field theory. A boundary condition is specified by a consistent collection of reflection coefficients for bulk fields on the disk together with a choice of an automorphism ω of the fusion rules that preserves conformal weights. Non-trivial automorphisms ω correspond to D-brane configurations for arbitrary conformal field theories.
متن کاملThe non-chiral fusion rules in rational conformal field theories
We introduce a general method in order to construct the non-chiral fusion rules which determine the operator content of the operator product algebra for rational conformal field theories. We are particularly interested in the models of the complementary D−like solutions of the modular invariant partition functions with cyclic center ZN . We find that the non-chiral fusion rules have a ZN−gradin...
متن کاملŝl(2)−1/2: A CASE STUDY
The construction of the non-logarithmic conformal field theory based on ŝl(2)−1/2 is revisited. Without resorting to free-field methods, the determination of the spectrum and fusion rules is streamlined and the βγ ghost system is carefully derived as the extended algebra generated by the unique finite-order simple current. A brief discussion of modular invariance is given and the Verlinde formu...
