Small Yukawa couplings in particle physics and cosmology from Type 1 string theory
Small Yukawa couplings in particle physics and cosmology from Type 1 string theory
Within the framework of Type I string theory we construct phenomenologically interesting models. The string theory is formulated in a 10 dimensional space of which 6 are compact and the anisotropies in the compact dimensions lead to a hierarchy of gauge and Yukawa couplings. We make use of this hierarchy to construct a model of inflationary particle physics and a consistent model for Dirac neutrino masses. The inflation model solves the strong CP and μ problems of the MSSM and predicts a range of allowed ratios for μ and the soft masses for the Higgs doublets. We demonstrate that it is possible to obtain Dirac masses in agreement with current experimental data.

Abstract
Within the framework of Type I string theory we construct phenomenologically interesting models. The string theory is formulated in a 10 dimensional space of which 6 are compact and the anisotropies in the compact dimensions lead to a hierarchy of gauge and Yukawa couplings. We make use of this hierarchy to construct a model of inflationary particle physics and a consistent model for Dirac neutrino masses. The inflation model solves the strong CP and μ problems of the MSSM and predicts a range of allowed ratios for μ and the soft masses for the Higgs doublets. We demonstrate that it is possible to obtain Dirac masses in agreement with current experimental data.
