(Anti)symmetric matter and superpotentials from IIBorientifolds

PDF Version Also Available for Download.

Description

We study the IIB engineering of N=1 gauge theories with unitary gauge group and matter in the adjoint and (anti)symmetric representations. We show that such theories can be obtained as Z{sub 2} orientifolds of certain Calabi-Yau A{sub 2} fibrations, and discuss the explicit T-duality transformation to an orientifolded Hanany-Witten construction. The low energy dynamics is described by a geometric transition of the orientifolded background. Unlike previously studied cases, we show that the orientifold 5-''plane'' survives the transition, thus bringing a nontrivial contribution to the effective superpotential. We extract this contribution by using matrix model results and compare with geometric data. ... continued below

Description

We study the IIB engineering of N=1 gauge theories with unitary gauge group and matter in the adjoint and (anti)symmetric representations. We show that such theories can be obtained as Z{sub 2} orientifolds of certain Calabi-Yau A{sub 2} fibrations, and discuss the explicit T-duality transformation to an orientifolded Hanany-Witten construction. The low energy dynamics is described by a geometric transition of the orientifolded background. Unlike previously studied cases, we show that the orientifold 5-''plane'' survives the transition, thus bringing a nontrivial contribution to the effective superpotential. We extract this contribution by using matrix model results and compare with geometric data. A Higgs branch of our models recovers the engineering of SO/Sp theories with adjoint matter through an O5-''plane'' T-dual to an O6-plane. We show that the superpotential agrees with that produced by engineering through an O5-''plane'' dual to an O4-plane, even though the orientifold of this second construction is replaced by fluxes after the transition.
