A Note on (Meta)stable Brane Configurations in MQCD
We examine the M-theory version of SQCD which is known as MQCD. In the IIA limit, this theory appears to have a supersymmetry-breaking brane configuration which corresponds to the meta-stable state of N = 1 SU(Nc) SQCD. However, the behavior at infinity of this non-supersymmetric brane construction differs from that of the supersymmetric ground state of MQCD. We interpret this to mean that it i...
متن کاملD6-branes and torsion
The D6-brane spectrum of type IIA vacua based on twisted tori T̃ 6 and RR background fluxes is analyzed. In particular, we compute the torsion factors of Hn(T̃ 6,Z) and describe the effect that they have on D6-brane physics. For instance, the fact that H3(T̃ 6,Z) contains ZN subgroups explains why RR tadpole conditions are affected by geometric fluxes. In addition, the presence of torsional (co)ho...
متن کاملComments on Brane Configurations with Semi-infinite D4 Branes
We consider four dimensional supersymmetric gauge field theories from brane configurations with the matter content given by semi-infinite D4 branes ending on both sides of NS branes. In M theory configuration, we discuss the splitting of the M5 brane into infinite cylindrical M5 branes (which decouple) and transversal M5 brane. The splitting condition appears naturally from the consistency of t...
متن کاملMirror Symmetries for Brane Configurations and Branes at Singularities
We study local mirror symmetry on non-compact Calabi-Yau manifolds (conifold type of singularities) in the presence of D3 brane probes. Using an intermediate brane setup of NS 5-branes ‘probed’ by D4 resp. D5 branes, we can explicitly T-dualize three isometry directions to relate a non-compact Calabi-Yau manifold to its local mirror. The intermediate brane setup is the one that is best suited t...
متن کاملD6-branes wrapping Kähler four-cycles
We construct supergravity duals of D6-branes wrapping Kähler four-cycles inside a Calabi-Yau threefold, CY3. We obtain the purely gravitational M-theory description, which turns out to be a Calabi-Yau fourfold, CY4. We also analyze the dynamics of a probe D6 in this background. 1 E-mail: [email protected] 2 E-mail: [email protected]
