Progress in Weakly Coupled String Phenomenology * † Disclaimer

The weakly coupled vacuum of E8⊗E8 heterotic string theory remains an attractive scenario for particle physics. The particle spectrum and the issue of dilaton stabilization are reviewed. A specific model for hidden sector condensation and supersymmetry breaking, that respects known constraints from string theory, is described, and its phenomenological and cosmological implications are discussed. Talk presented at Spacetime Odyssey 2001, University of Michigan, Ann Arbor, MI, May 21-14, 2001, to be published in the proceedings.
