Chiral supersymmetric models on an orientifold of Z4 x Z2 with intersecting D6-branes
Abstract
We investigate intersecting D6-branes on an orientifold of type IIA theory in the orbifold background T6/(Z4 x Z2) with the emphasis on finding chiral spectra. RR tadpole cancellation conditions and the scalar potential at disc level are computed. The general chiral spectrum is displayed, and two supersymmetric models with a Pati-Salam group are shown,one with four generations and the other one with three generations and exactly the chiral matter content of the SM plus right handed neutrinos.
