Deducing Lfermion at MGUT using Low Energy Data or Towards a Theory of Fermion Masses
Stuart Raby
Abstract
In the last 20 years we have accumulated an enormous amount of data on elementary particles and their interactions. This data serves two purposes: to fix the phenomenological parameters of the Standard Model [SM] and to verify that the SM is an excellent description of nature. It is our goal to understand the origin of these many arbitrary parameters. In this talk we consider a supersymmetric [SUSY] SO(10) grand unified theory [GUT]. We present a straightforward procedure, incorporating a general operator analysis, which allows us to use low energy data to determine the fermionic sector of the theory at the GUT scale.
