A Non-perturbative Description of the Gimon-Polchinski Orientifold

TL;DR

This paper explores non-perturbative quantum effects in a T-dual Gimon-Polchinski orientifold, revealing how orientifold planes split into pairs of seven branes and how intersecting planes behave under quantum corrections.

Contribution

It provides a non-perturbative description of the Gimon-Polchinski orientifold, showing how quantum effects modify the brane and orientifold plane configurations.

Findings

Orientifold planes split into pairs of nearly parallel seven branes due to quantum effects.

Intersecting orientifold planes result in a single pair of seven branes, not two.

The results are interpreted through the dynamics on a three brane probe.

Abstract

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 intersecting orientifold planes, instead of giving rise to two pairs of intersecting seven branes, gives just one pair of seven branes, each representing a pair of nearly orthogonal seven branes smoothly joined to each other near the would be intersection point. Interpretation of these results from the point of view of the dynamics on a three brane probe is also discussed.
