Duality for SUxSO and SUxSp via Branes

الأصل · EN

Using a six-orientifold, fourbranes and four fivebranes in type IIA string theory we construct N=1 supersymmetric gauge theories in four dimensions with product group SU(M)× SO(N) or SU(M)× Sp(2N), a bifundamental flavor and quarks. We obtain the Seiberg dual for these theories and rederive it via branes. To obtain the complete dual group via branes we have to add semi-infinite fourbranes. We propose that the theory derived from branes has a meson deformation switched on. This deformation implies higgsing in the dual theory. The addition of the semi-infinite fourbranes compensates this effect.
