Description

We consider the possibility of constructing phenomenologically viable vacua based on the Z7 orbifold. The acceptable ones are classified and drastically reduced by the use of equivalence operations between them. The results are applicable for SU(3)xSU(2)xU(1)n and grand unification schemes. Finally we discuss some physically relevant properties of the Z7 orbifold, in particular the possibility of having just one (3,2) quark representation in the untwisted sector, which allows for a natural explanation of the Cabbibo angle.
