From 5D SO(10) To Flipped SU(5)

Abstract:We discuss a 5D SO(10) model model,that is broken to flipped SU(5) on the hidden brane.Via bulk mass term,the fermion's mass and mixing hierarchy is explained.As for the gauge coupling unification is realized with a higher compafication scale.By introducing a new dynamics on the hidden brane,SUSY is broken dynamically,with proper phenomenological result.Further,the life of proton is long enough in our model.
