M theory on orientifolds of K3 x S1.

چکیده
We present several Orientifolds of M-Theory on K 3 × S 1 by additional projections with respect to the finite abelian automorphism groups of K 3. The resulting models correspond to anomaly free theories in six dimensions. We construct explicit examples which can be interpreted as models with eight, four, two and one vector multiplets and N = 1 supersymmetry in six dimensions.

Non-perturbative K3 Orientifolds with NS-NS B-flux
We consider non-perturbative six dimensional N = 1 space-time supersymmetric orientifolds of Type IIB on K3 with non-trivial NS-NS B-flux. All of these models are non-perturbative in both orientifold and heterotic pictures. Thus, some states in such compactifications arise in “twisted” open string sectors which lack world-sheet description in terms of D-branes. We also discuss their dual F-theo...
متن کاملOrientifolds of K3 and Calabi-Yau Manifolds with Intersecting D-branes
We investigate orientifolds of type II string theory on K3 and Calabi-Yau 3-folds with intersecting D-branes wrapping special Lagrangian cycles. We determine quite generically the chiral massless spectrum in terms of topological invariants and discuss both orbifold examples and algebraic realizations in detail. Intriguingly, the developed techniques provide an elegant way to figure out the chir...

We study string theory propagating on R6×K3 by constructing orientifolds of Type IIB string theory compactified on the T /ZN orbifold limits of the K3 surface. This generalises the Z2 case studied previously. The orientifold models studied may be divided into two broad categories, sometimes related by T–duality. Models in category A require either both D5– and D9– branes, or only D9–branes, for...

متن کاملMultiple Realisations of N=1 Vacua in Six Dimensions
A while ago, examples of N=1 vacua in D=6 were constructed as orientifolds of Type IIB string theory compactified on the K3 surface. Among the interesting features of those models was the presence of D5–branes behaving like small instantons, and the appearance of extra tensor multiplets. These are both non–perturbative phenomena from the point of view of Heterotic string theory. Although the or...
