From strings to the MSSM

Abstract

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 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.

Based on invited talks given at the conferences SUSY07 (Karlsruhe), Planck08 (Barcelona), String-Phenomenology08 (Philadelphia), PASCOS08 (Waterloo) and SUSY08 (Seoul). To be published in "Supersymmetry on the Eve of the LHC", a special volume of EPJC dedicated to the memory of Julius Wess
