Operator product expansion in the SL 2 conformal field theory

چکیده
We discuss the operator product expansion (OPE) in the models with the SL2 affine symmetry. For this purpose, we calculate the correlation functions of the primary fields with definite SL2 weights. By using them and extending the arguments in the literature, we show that the OPE with one primary field in a degenerate representation is correctly obtained. We also study the OPE among the primary fields in the spectrum recently proposed for the SL(2, R) WZW model. We argue that the OPE with one primary field in a discrete series unitary representation is consistent with the tensor products of the SL(2, R) representations. The cases involving the winding sectors are also discussed. May 2001 [email protected] [email protected]

Three-point functions and operator product expansion in the SL(2) conformal field theory
In the SL(2) conformal field theory, we write down and analyze the analytic expression of the three-point functions of generic primary fields with definite SL(2) weights. Using these results, we discuss the operator product expansion in the SL(2, R) WZW model. We propose a prescription of the OPE, the classical limit of which is in precise agreement with the tensor products of the representatio...
متن کاملOperator product expansion in SL(2) conformal field theory
In the conformal field theories having affine SL(2) symmetry, we study the operator product expansion (OPE) involving primary fields in highest weight representations. For this purpose, we analyze properties of primary fields with definite SL(2) weights, and calculate their twoand three-point functions. Using these correlators, we show that the correct OPE is obtained when one of the primary fi...

In logarithmic conformal field theory, primary fields come together with logarithmic partner fields on which the stress-energy tensor acts non-diagonally. Exploiting this fact and global conformal invariance of two-and three-point functions, operator product expansions of logarithmic operators in arbitrary rank logarithmic conformal field theory are derived.

We review the construction of braided tensor categories and modular tensor categories from representations of vertex operator algebras, which correspond to chiral algebras in physics. The extensive and general theory underlying this construction also establishes the operator product expansion for intertwining operators, which correspond to chiral vertex operators, and more generally, it establi...
