# Orientifolds of K3 and Calabi-Yau manifolds with intersecting D-branes

@article{Blumenhagen2002OrientifoldsOK, title={Orientifolds of K3 and Calabi-Yau manifolds with intersecting D-branes}, author={Ralph Blumenhagen and Volker Braun and Boris Kors and Dieter Lust}, journal={Journal of High Energy Physics}, year={2002}, volume={2002}, pages={026-026} }

We investigate orientifolds of type II string theory on K3 and Calabi-Yau 3-folds with intersecting D-branes wrapping special lagrangian cycles. We determine quite generically the chiral massless spectrum in terms of topological invariants and discuss both orbifold examples and algebraic realizations in detail. Intriguingly, the developed techniques provide an elegant way to figure out the chiral sector of orientifold models without computing any explicit string partition function. As a new…
