Supersymmetric heterotic string backgrounds
We present the main features of the solution of the gravitino and dilatino Killing spinor equations derived in hep-th/0510176 and hep-th/0703143 which have led to the classification of geometric types of all type I backgrounds. We then apply these results to the supersymmetric backgrounds of the heterotic string. In particular, we solve the gaugino Killing spinor equation together with the othe...
متن کاملThe Spinorial Geometry of Supersymmetric Heterotic String Backgrounds
We determine the geometry of supersymmetric heterotic string backgrounds for which all parallel spinors with respect to the connection ∇̂ with torsion H , the NS⊗NS three-form field strength, are Killing. We find that there are two classes of such backgrounds, the null and the timelike. The Killing spinors of the null backgrounds have stability subgroups K ⋉R 8 in Spin(9, 1), for K = Spin(7), SU...
متن کاملHeterotic supersymmetric backgrounds with compact holonomy revisited
We simplify the classification of supersymmetric solutions with compact holonomy of the Killing spinor equations of heterotic supergravity using the field equations and the additional assumption that the 3-form flux is closed. We determine all the fractions of supersymmetry that the solutions preserve and find that there is a restriction on the number of supersymmetries which depends on the iso...
متن کاملLittle String Theories in Heterotic Backgrounds ⋆
We study Little String Theories (LST) with N = (1, 0) supersymmetry arising, in a suitable double scaling limit, from 5-branes in heterotic string theory or in the heterotic-like type II/(−) F L × shift. The limit in question, previously studied in the type II case, is such that the resulting holographically dual pairs, i.e. bulk string theory and LST can be considered to be weakly coupled. In ...
متن کاملHeterotic string backgrounds and CP violation
In the framework of ZN orbifolds, we discuss effects of heterotic string backgrounds including discrete Wilson lines on the Yukawa matrices and their connection to CP violation.
