TL;DR
This paper extends the theoretical framework of Gepner Model orientifolds to include even levels and complex parity dressings, providing explicit formulas and a supersymmetric Pati-Salam model example.
Contribution
It generalizes previous descriptions of Gepner Model orientifolds, offering explicit amplitude expressions and tadpole conditions for more complex configurations.
Findings
Explicit Klein-bottle, annulus, and Moebius strip amplitudes
General tadpole cancellation conditions
Constructed a supersymmetric Pati-Salam model
Abstract
In this note we generalize the description of simple current extended Gepner Model orientifolds as presented in hep-th/0401148 to the case of even levels and non-trivial dressings of the parity transformation. We provide a comprehensive list of all the important ingredients for the construction of such orientifolds. Namely we present explicit expressions for the Klein-bottle, annulus and Moebius strip amplitudes and derive the general tadpole cancellation conditions. As an example we construct a supersymmetric Pati-Salam like model.
