چکیده
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 involves background RR and NS fluxes. We consider in detail an orientifold of K3×T 2 with background fluxes. After a combination of T and S-dualities, this type IIB orientifold is mapped to a compactification of the SO(32) heterotic string on a non-Kähler space with torsion.

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 کاملDomain Wall Junctions and 1/4-Supersymmetric States
We study N = 1 SUSY theories in four dimensions with multiple discrete vacua, which admit solitonic solutions describing segments of domain walls meeting at one-dimensional junctions. We show that there exist solutions preserving one quarter of the underlying supersymmetry – a single Hermitian supercharge. We derive a BPS bound for the masses of these solutions and construct a solution explicit...
