چکیده
It is known previously that the operator product expansion (OPE) between first [Formula: see text] multiplet and itself contains second in supersymmetric coset model. In this paper, by using their realizations terms of various fermions, we compute four kinds OPEs multiplets for fixed text], where group text]. By supersymmetrizing above superspace Jacobi identities currents, determine OPE completely. The right-hand side multiplets: singlet superspin-[Formula: triplet description decoupling spin-[Formula: current superconformal algebra are also described.

Fermionic coset realization of the critical Ising model.
We obtain an explicit realization of all the primary fields of the Ising model in terms of a conformal field theory of constrained fermions. The four-point correlators of the energy, order and disorder operators are explicitly calculated. ∗On leave of absence from the Universidad Nacional de La Plata, Argentina
متن کاملDuality in deformed coset fermionic models
We study the SU(2)k/U(1)-parafermion model perturbed by its first thermal operator. By formulating the theory in terms of a (perturbed) fermionic coset model we show that the model is equivalent to interacting WZW fields modulo free fields. In this scheme, the order and disorder operators of the Zk parafermion theory are constructed as gauge invariant composites. We find that the theory present...
متن کاملFermionic Coset Models as Topological Models
By considering the fermionic realization of G/H coset models, we show that the partition function for the U(1)/U(1) model defines a Topological Quantum Field Theory and coincides with that for a 2dimensional Abelian BF system. In the non-Abelian case, we prove the topological character of G/G coset models by explicit computation, also finding a natural extension of 2-dimensional BF systems with...
متن کاملLine bundles in supersymmetric coset models
The scalars of a N = 1 supersymmetric σ-model in 4 dimensions parametrize a Kähler manifold. This Kähler manifold often takes the form of a tensor product of bundles over a basis manifold. When one of these bundles is a line bundle, the corresponding Kähler form has to satisfy a quantization condition when the topology of the submanifold is non-trivial. This results in a consistency restriction...
متن کاملNon-Supersymmetric Attractors in Symmetric Coset Spaces
The attractor mechanism for supersymmetric (BPS) black holes was discovered in 1995 [1]: at the horizon of a supersymmetric black hole, the moduli are completely determined by the charges of the black hole, independent of their asymptotic values. In 2005, Sen showed that all extremal black holes, both supersymmetric and non-supersymmetric (non-BPS), exhibit attractor behavior [2]: it is a resul...
