Heterotic on Half-flat
نویسندگان
چکیده
We study the effective action of the heterotic string compactified on particular half-flat manifolds which arise in the context of mirror symmetry with NS-NS flux. We explicitly derive the superpotential and Kähler potential at lowest order in α by a reduction of the bosonic action. The superpotential contains new terms depending on the Kähler moduli which originate from the intrinsic geometrical flux of the half-flat manifolds. A generalized Gukov formula, valid for all manifolds with SU(3) structure, is derived from the gravitino mass term. For the half-flat manifolds it leads to a superpotential in agreement with our explicit bosonic calculation. We also discuss the inclusion of gauge fields.

Heterotic String Compactifications on Half-flat Manifolds II
In this paper, we continue the analysis of heterotic string compactifications on half-flat mirror manifolds by including the 10-dimensional gauge fields. It is argued, that the heterotic Bianchi identity is solved by a variant of the standard embedding. Then, the resulting gauge group in four dimensions is still E6 despite the fact that the Levi-Civita connection has SO(6) holonomy. We derive t...
متن کاملA Note on Moduli Stabilisation in Heterotic Models in the Presence of Matter Fields
In this brief note we analyse a toy model which can be derived from heterotic string compactifications on half-flat manifolds with SU(3) structure at first order in α (ie including matter fields). We show that for this model, finding solutions with viable gauge group poses the same problems as finding solutions in the absence of matter fields.
متن کاملOn Fractional Instanton Numbers in Six Dimensional Heterotic E8 × E8 Orbifolds
We show how the level matching condition in six dimensional, abelian and supersymmetric orbifolds of the E8 × E8 heterotic string can be given equivalently in terms of fractional gauge and gravitational instanton numbers. This relation is used to restate the classification of the orbifolds in terms of flat bundles away from the orbifold singularities under the constraint of the level matching c...
متن کاملTopological Phases of the Heterotic String ⋆
We analyze the phase structure of topological Calabi–Yau manifolds defined on the moduli space of instantons. We show in this framework that topological vacua describe new phases of the Heterotic String theory in which the flat directions corresponding to complex deformations are lifted. We also briefly discuss the phase structure of non–Kähler manifolds.
متن کاملZ3 orbifolds of the SO(32) heterotic string: 1-Wilson-line embeddings
We consider compactification of the SO(32) heterotic string on a 6-dimensional Z3 orbifold with one discrete Wilson line. A complete set of all possible embeddings is given. The unbroken subgroups of SO(32) are tabulated. The extended gauge symmetry SU(3), recently discussed by J. E. Kim [hep-th/0301177] for semi-realistic E8 × E8 heterotic string models, occurs for several embeddings, as well ...
