Local models for intersecting brane worlds
Angel M. Uranga
We describe the construction of configurations of D6-branes wrapped on compact 3-cycles intersecting at points in non-compact Calabi-Yau threefolds. Such constructions provide loca…
Gauging Away the Strong CP Problem
G. Aldazabal, L. E. Ibanez, A. M. Uranga
We propose a new solution to the strong-CP problem. It involves the existence of an unbroken gauged symmetry whose gauge boson gets a Stuckelberg mass term by combining wi…
Localized instabilities at conifolds
Angel M. Uranga
We consider the M-theory lifts of configurations of type IIA D6-branes intersecting at angles. In supersymmetry preserving cases, the lifts correspond to special holonomy geometrie…
D-brane, fluxes and chirality
Angel M. Uranga
We describe a topological effect on configurations of D-branes in the presence of NS-NS and RR field strength fluxes. The fluxes induce the appearance of chiral anomalies on lower…
