From strings to the MSSM. (English) Zbl 1189.81185
Summary: We review recent progress in embedding the supersymmetric standard model into string theory. We discuss how, with the incorporation of certain aspects of grand unification, a search strategy can be developed that allows one to efficiently find rather large numbers of promising string vacua. Global string-derived models with the following features are discussed: (i) exact MSSM spectrum below the unification scale; (ii) $$R$$-parity; (iii) hierarchical Yukawa couplings with non-trivial mixing; (iv) solution to the $$\mu$$ problem; (v) see-saw suppressed neutrino masses.
