M Theory , Orientifolds and G - Flux
We study the properties of M and F theory compactifications to three and four dimensions with background fluxes. We provide a simple construction of supersymmetric vacua, including some with orientifold descriptions. These vacua, which have warp factors, typically have fewer moduli than conventional Calabi-Yau compactifications. The mechanism for anomaly cancellation in the orientifold models i...
متن کاملF Theory Orientifolds, M Theory Orientifolds, and Twisted Strings
Orientifolds of the type IIB superstring that descend from F theory and M theory orbifolds are studied perturbatively. One finds strong evidence that a previously ignored twisted open string is required in these models. An attempt is made to interpret the J type torsion in F theory where one finds a realization of Gimon and Johnson’s models which does not require these twisted strings. S-dualit...

متن کاملOrientifolds , M – Theory , and the ABCD ’ s of the Enhançon
Supergravity solutions related to large N SU(N) pure gauge theories with eight supercharges have recently been shown to give rise to an “enhançon”, a new type of hypersurface made of D–branes. We show that enhançons also arise in similar situations pertaining to SO(2N+1), USp(2N) and SO(2N) gauge theories, using orientifolds. Enhançons therefore appear to come in types A, B, C, and D. The latte...
متن کاملBrane/Flux Interactions in Orientifolds
Combining the benefits of D-branes and background fluxes in string compactifications opens up the possibility to explore phenomenologically interesting brane world models with stabilized moduli. However, it is difficult to determine interaction effects among open strings and fluxes in the effective action. We derive the full bosonic Lagrangian of a (spontaneously broken) N = 4 supersymmetric mo...
