Dn Quivers From Branes
D-branes can end on orbifold planes if the action of the orbifold group includes (−1)FL . We consider configurations of D-branes ending on such orbifolds and study the low-energy theory on their worldvolume. We apply our results to gauge theories with eight supercharges in three and four dimensions. We explain how mirror symmetry for N = 4 d = 3 gauge theories with gauge group Sp(k) and matter ...
متن کاملCascading Quivers from Decaying D-branes
We use an argument analogous to that of Kachru, Pearson and Verlinde to argue that cascades in L a,b,c quiver gauge theories always preserve the form of the quiver, and that all gauge groups drop at each step by the number M of fractional branes. In particular, we demonstrate that an NS5-brane that sweeps out the S 3 of the base of L
متن کاملD-branes on Singularities: New Quivers from Old
In this paper we present simplifying techniques which allow one to compute the quiver diagrams for various D-branes at (non-Abelian) orbifold singularities with and without discrete torsion. The main idea behind the construction is to take the orbifold of an orbifold. Many interesting discrete groups fit into an exact sequence N → G → G/N . As such, the orbifold M/G is easier to compute as (M/N...
متن کاملSix-dimensional DN theory and four-dimensional SO–USp quivers
We realize four-dimensional N = 2 superconformal quiver gauge theories with alternating SO and USp gauge groups as compactifications of the six-dimensional DN theory with defects. The construction can be used to analyze infinitely stronglycoupled limits and S-dualities of such gauge theories, resulting in a new class of isolated four-dimensional N = 2 superconformal field theories with SO(2N) f...
متن کاملSUSY Quivers, Intersecting Branes and the Modest Hierarchy Problem
We present a class of chiral non-supersymmetric D = 4 field theories in which quadratic divergences appear only at two loops. They may be depicted as “SUSY quivers” in which the nodes represent a gauge group with extended e.g., N = 4 SUSY whereas links represent bifundamental matter fields which transform as chiral multiplets with respect to different N = 1 subgroups. One can obtain this type o...
