Unitary minimal models of SW ( 3 / 2 , 3 / 2 , 2 ) superconformal algebra and manifolds of G 2 holonomy
نویسنده
چکیده
The SW(3/2, 3/2, 2) superconformal algebra is a W algebra with two free parameters. It consists of 3 superconformal currents of spins 3/2, 3/2 and 2. The algebra is proved to be the symmetry algebra of the coset su(2)⊕su(2)⊕su(2) su(2) . At the central charge c = 10 2 the algebra coincides with the superconformal algebra associated to manifolds of G2 holonomy. The unitary minimal models of the SW(3/2, 3/2, 2) algebra and their fusion structure are found. The spectrum of unitary representations of the G2 holonomy algebra is obtained.

On the symmetries of special holonomy sigma models
In addition to superconformal symmetry, (1, 1) supersymmetric two-dimensional sigma models on special holonomy manifolds have extra symmetries that are in one-to-one correspondence with the covariantly constant forms on these manifolds. The superconformal algebras extended by these symmetries close as W-algebras, i.e. they have field-dependent structure functions. It is shown that it is not pos...
متن کاملSuperconformal Field Theories for Compact Manifolds with Spin(7) Holonomy
We present a construction of superconformal field theories for manifolds with Spin(7) holonomy. Geometrically these models correspond to the realization of Spin(7) manifolds as anti-holomorphic quotients of Calabi-Yau fourfolds. Describing the fourfolds as Gepner models and requiring anomaly cancellation we determine the resulting Betti numbers of the Spin(7) superconformal field theory. As in ...
متن کاملKac and new determinants for fractional superconformal algebras.
We derive the Kac and new determinant formulae for an arbitrary (integer) level K fractional superconformal algebra using the BRST cohomology techniques developed in conformal field theory. In particular, we reproduce the Kac determinants for the Virasoro (K = 1) and superconformal (K = 2) algebras. For K ≥ 3 there always exist modules where the Kac determinant factorizes into a product of more...
متن کاملRational Conformal Field Theories With G 2 Holonomy
We study conformal field theories for strings propagating on compact, seven-dimensional manifolds with G 2 holonomy. In particular, we describe the construction of rational examples of such models. We argue that analogues of Gepner models are to be constructed based not on N = 1 minimal models, but on Z 2 orbifolds of N = 2 models. In Z 2 orbifolds of Gepner models times a circle, it turns out ...
متن کاملRepresentation Theory of Superconformal Algebras and the Kac-roan-wakimoto Conjecture
We study the representation theory of the superconformal algebra Wk(g, fθ) associated to a minimal gradation of g. Here, g is a simple finite-dimensional Lie superalgebra with a non-degenerate even supersymmetric invariant bilinear form. Thus, Wk(g, fθ) can be the Virasoro algebra, the Bershadsky-Polyakov algebra, the Neveu-Schwarz algebra, the BershadskyKnizhnik algebras, the N = 2 superconfor...
