Orientifolds, Branes, and Duality of 4D Gauge Theories
نویسندگان
چکیده
Recently, a D–brane construction in type IIA string theory was shown to yield the electric/magnetic duality of four dimensional N=1 supersymmetric U(Nc) gauge theories with Nf flavours of quark. We present here an extension of that construction which yields the electric/magnetic duality for the SO(Nc) and USp(Nc) gauge theories with Nf quarks, by adding an orientifold plane which is consistent with the supersymmetry. Due to the intersection of the orientifold plane with the NS–NS fivebranes already present, new features arise which are crucial in determining the correct final structure of the dualities.

New IR Dualities in Supersymmetric Gauge Theory in Three Dimensions
We present nontrivial examples of d = 3 gauge theories with sixteen and eight supercharges which are infrared dual at special points in the moduli space. This duality is distinct from mirror symmetry. To demonstrate duality we construct the gauge theories of interest using D2-branes and orientifolds and then consider their lift to M-theory. We also discuss the strong coupling limit of orientifo...
متن کاملSuperstring Orientifolds with Torsion: O5 Orientifolds of Torus Fibrations and their Massless Spectra
Using a “Superstrings with Torsion” type description, we study a class of IIB orientifolds in which spacefilling O5 planes and D5 branes wrap the T 2 fiber in a warped modification of the product of 4D Minkowski space and a T 2 fibration. For the case that the base is T , we provide examples that preserve 4D N = 1, 2, and 3 supersymmetry, both with internal RR flux, and with a combination of in...
متن کاملOrientifolds in N = 2 Liouville Theory and its Mirror
We consider unoriented strings in the supersymmetric SL(2,R)/U(1) coset, which describes the two-dimensional Euclidean black hole, and its mirror dual N = 2 Liouville theory. We analyze the orientifolds of these theories from several complementary points of view: the parity symmetries of the worldsheet actions, descent from known AdS3 parities, and the modular bootstrap method (in some cases we...
متن کاملA Large N Duality via a Geometric Transition
We propose a large N dual of 4d, N = 1 supersymmetric, SU(N) Yang-Mills with adjoint field Φ and arbitrary superpotential W (Φ). The field theory is geometrically engineered via D-branes partially wrapped over certain cycles of a non-trivial Calabi-Yau geometry. The large N , or low-energy, dual arises from a geometric transition of the Calabi-Yau, where the branes have disappeared and have bee...
متن کاملLarge N Gauge Theories from Orientifolds with NS-NS B-flux
We consider D-branes and orientifold planes embedded in non-compact (orbifolded) space-time. We point out that even in the non-compact cases we can turn on non-zero (quantized) NS-NS antisymmetric B-field. In particular, we study the effect of the B-field on four dimensional large N gauge theories from orientifolds. Thus, in theories with both D3and D7-branes, the effect of the B-field is non-t...
