Fusion Rules for ŝl ( 2 | 1 ; C ) at Fractional Level k = − 1 / 2

چکیده
We calculate fusion rules for the admissible representations of the superalgebra ŝl(2|1;C)k at fractional level k = −1/2 in the Ramond sector. By representing 3point correlation functions involving a singular vector as the action of differential operators on the sl(2|1;C) invariant 3-point function, we obtain conditions on permitted quantum numbers involved. We find that in this case the primary fields close under fusion.

متن کاملA Note on Decoupling Conditions for Generic Level ŝl ( 3 ) k and Fusion Rules
We find the solution of the sl(3) k singular vector decoupling equations on 3–point functions for the particular case when one of the fields is of weight w 0 · kΛ 0. The result is a function with non-trivial singularities in the flag variables, namely a linear combination of 2 F 1 hypergeometric functions. This calculation fills in a gap in [1] and confirms the sl(3) k fusion rules determined t...
متن کاملFUSION IN FRACTIONAL LEVEL ŝl(2)-THEORIES WITH k =−
The fusion rules of conformal field theories admitting an ŝl(2)-symmetry at level k = − 1 2 are studied. It is shown that the fusion closes on the set of irreducible highest weight modules and their images under spectral flow, but not when “highest weight” is replaced with “relaxed highest weight”. The fusion of the relaxed modules, necessary for a well-defined û(1)-coset, gives two families of...
متن کاملModular Transformations and Invariants in the Context of Fractional Level
The modular transformation properties of admissible characters of the affine superalgebra ŝl(2|1;C)k at fractional level k = 1/u− 1, u ∈ N \ {1} are presented. All modular invariants for u = 2 and u = 3 are calculated explicitly and an A-series and D-series of modular invariants emerge.
متن کاملAn Extension of the Character Ring of sl(3) and Its Quantisation
We construct a commutative ring with identity which extends the ring of characters of finite dimensional representations of sl(3). It is generated by characters with values in the group ring Z[W̃ ] of the extended affine Weyl group of ŝl(3)k at k 6∈ Q. The ‘quantised’ version at rational level k + 3 = 3/p realises the fusion rules of a WZW conformal field theory based on admissible representatio...
