F-theory and the Gimon-Polchinski Orientifold
نویسنده
چکیده
We establish the equivalence of the Gimon-Polchinski orientifold and F-theory on an elliptically fibered Calabi-Yau three fold on base CP 1 × CP 1 by comparing the gauge symmetry breaking pattern, local deformations in the moduli space, as well as the axiondilaton background in the weak coupling limit in the two theories. We also provide an explanation for an apparent discrepancy between the F-theory and the orientifold results for constant coupling configuration.

Non-perturbative Enhanced Gauge Symmetries in the Gimon-Polchinski Orientifold
We study the enhanced gauge symmetries at constant couplings in the moduli space of the Gimon-Polchinski Orientifold. We show that whenever there is a singularity of
متن کاملA 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 کاملTensors from K3 Orientifolds
Recently Gimon and Johnson [1] and Dabholkar and Park [2] have constructed Type I theories on K3 orbifolds. The spectra differ from that of Type I on a smooth K3, having extra tensors. We show that the orbifold theories cannot be blown up to smooth K3’s, but rather Z2 orbifold singularities always remain. Douglas’s recent proposal to use D-branes as probes is useful in understanding the geometr...
متن کاملConsistency conditions for orientifolds and D-manifolds.
We study superstrings with orientifold projections and with generalized open string boundary conditions (D-branes). We find two types of consistency condition, one related to the algebra of Chan-Paton factors and the other to cancellation of divergences. One consequence is that the Dirichlet 5-branes of the Type I theory carry a symplectic gauge group, as required by string duality. As another ...
متن کاملOn the Complementarity of F-theory, Orientifolds, and Heterotic Strings
We study F-theory duals of six dimensional heterotic vacua in extreme regions of moduli space where the heterotic string is very strongly coupled. We demonstrate how to use orientifold limits of these F-theory duals to regain a perturbative string description. As an example, we reproduce the spectrum of a T /ZZ4 orientifold as an F-theory vacuum with a singular K3 fibration. We relate this vacu...
