On the M-theory Interpretation of Orientifold Planes
نویسنده
چکیده
We obtain an M–theory interpretation of different IIA orientifold planes by compactifying them on a circle and use a chain of dualities to get a new IIA limit of these objects using this circle as the eleventh dimension. Using the combination of the two IIA description, we give an interpretation for all orientifold four-planes in M-theory, including a mechanism for freezing M5branes at singularities. email: [email protected] 1

A Non-perturbative Description of the Gimon-Polchinski Orientifold
A T-dual version of the Gimon-Polchinski orientifold can be described by a configuration of intersecting Dirichlet seven branes and orientifold seven planes in the classical limit. We study modification of this background due to quantum corrections. It is shown that non-perturbative effects split each orientifold plane into a pair of nearly parallel seven branes. Furthermore, a pair of intersec...
متن کاملGravitational Couplings for Gop-planes and Y-op-planes
The results that this paper presents are about gravitational couplings for generalized orientifold planes (GOp-planes) and y-deformed orientifold planes (yOpplanes). The usual orientifold planes do not have gauge fields on their worldvolumes and . The generalized orientifold planes that this paper consider have SO(2k) Yang-Mills gauge fields-bundles over their corresponding worldvolumes. The ai...
متن کاملOrientifold Planes, Type I Wilson Lines and Non-BPS D-branes
There is a longstanding puzzle concerned with the existence of Õp − planes with p ≥ 6, which are orientifold p-planes of negative charge with stuck Dp-branes. We study the consistency of configurations with various orientifold planes and propose a resolution to this puzzle. It is argued that Õ6 − -planes are possible in massive IIA theory with odd cosmological constant, while Õ7 − -planes and Õ...
متن کاملNew 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 کاملGravitational couplings of orientifold planes
We reanalyse the gravitational couplings of the perturbative orientifold planes Op, Op (and D-branes). We first compute their D−1 instantonic corrections for p = 3. Then, by using U-dualities, we obtain the Wess-Zumino terms of orientifolds with RR flux for p ≤ 5. The expressions for the effective actions can be partially checked via M-theory. We point out a previous oversimplification and we s...
