Flipped image from image orbifold with Wilson line Original Research Article

We construct a three family flipped image model from the heterotic string theory compactified on the image orbifold with one Wilson line. The gauge group is image. This model does not derive any non-Abelian group except image from image, which is possible only for two cases in case of one shift V, one in image and the other in image. We present all possible Yukawa couplings. We place the third quark family in the twisted sectors and two light quark families in the untwisted sector. From the Yukawa couplings, the model provides the R-parity, the doublet–triplet splitting, and one pair of Higgs doublets. It is also shown that quark and lepton mixings are possible. So far we have not encountered a serious phenomenological problem. There exist vector-like flavor image exotics (including image color exotics and image electromagnetic exotics) and image vector-like singlet exotics with image which can be removed near the GUT scale. In this model, image at the full unification scale.
