Intersecting Brane World From Type I Compactification
We elaborate that general intersecting brane models on orbifolds are obtained from type I string compactifications and their T -duals. Symmetry breaking and restoration occur via recombination and parallel separation of branes, preserving supersymmetry. The Ramond– Ramond tadpole cancelation and the toron quantization constrain the spectrum as a branching of the adjoints of SO(32), up to orbifo...
متن کاملD6-brane Splitting on Type IIA Orientifolds
We study the open-string moduli of supersymmetric D6-branes, addressing both the string and field theory aspects of D6-brane splitting on Type IIA orientifolds induced by open-string moduli Higgsing (i.e., their obtaining VEVs). Specifically, we focus on the Z 2 × Z 2 ori-entifolds and address the symmetry breaking pattern for D6-branes parallel with the orientifold 6-planes as well as those po...
متن کاملIntersecting Brane Landscape by Vladimir
This thesis studies intersecting brane models, which are a class of quasi-realistic compactifications of string theory. Techniques are developed for exploring the complete space of intersecting brane models on an orientifold. The classification of all solutions for the widely-studied T 6/Z 2 x Z2 orientifold is made possible by computing all combinations of branes with negative tadpole contribu...
متن کاملIntersecting Brane Models and Cosmology
We discuss the application of general features of intersecting brane model constructions in cosmology. In particular, we describe a scenario for D-term inflation which arises straightforwardly in IBM constructions wherein open non-vectorlike strings play the role of the inflaton. We also show that baryogenesis driven by hidden sector mixed anomalies can naturally arise in intersecting brane mod...
