Model Building, .. We observed that only 19 right-mover lattices lead to models with . spacetime supersymmetry, and that some of them arise in certain . orbifold compactifications. In this chapter, we discuss explicit models belonging to two of these 19 classes of covariant lattice models, one class corresponding

Summary, Also, it was found that once a right-mover lattice is fixed, modular invariance requires that the set of possible left-mover lattices forms a genus. The result is that there are in total 99 right-mover lattices which may lead to chiral models, and only 19 of them lead to . spacetime supersymmetry.

Jeff Z. Pan,Diego Calvanese,Yuting ZhaoWe also considered some generic phenomenological properties of these models, such as discrete flavor and R-symmetries, and also gave spectra of three-generation models. Finally, we studied how the equivalence between certain covariant lattice and twist-orbifold models fits into our picture, and foun
