Probing Orientifold Behavior Near NS Branes

TL;DR

This paper investigates how NS 5 branes influence orientifold behavior, particularly focusing on charge changes when the orientifold interacts with a stack of NS branes in a regularized CHS geometry.

Contribution

It introduces a method to analyze the impact of NS branes on orientifold charge dynamics using open string effects in a regularized CHS background.

Findings

NS branes induce charge shifts in orientifolds

Open string effects reveal charge change mechanisms

Interaction with NS branes modifies orientifold properties

Abstract

The effect of NS 5 branes on an orientifold is studied. The orientifold is allowed to pass through a pile of k NS branes forming a regularized CHS geometry. Its effect on open strings in its vicinity is used to study the change in the orientifold charge induced by the NS branes.
