Gravitational Couplings for Generalized Orientifold Planes
arXiv:hep-th/0006076
Abstract
The Wess-Zumino action for generalized orientifold planes (GOp-planes) is presented and a series power expantion is realized from which processes that involves GOp-planes, RR-forms, gravitons and gaugeons, are obtained. Finally non-standard GOp-planes are showed.
