Chiral Supersymmetric Gepner Model Orientifolds

  title={Chiral Supersymmetric Gepner Model Orientifolds},
  author={Ralph Blumenhagen and Timo Weigand},
We explicitly construct A-type orientifolds of supersymmetric Gepner models. In order to reduce the tadpole cancellation conditions to a treatable number we first extend explicitly the generic results for the one-loop Klein bottle, annulus and Möbius strip amplitudes to simple current extensions of Gepner models. Equipped with these formulas, we discuss two examples in detail to provide evidence that in this setting certain features of the MSSM like unitary gauge groups with large enough rank… CONTINUE READING
