Some Topics in Grand Unified Models and the Cosmological Baryon Asymmetry


Reiss, David Benjamin (1981) Some Topics in Grand Unified Models and the Cosmological Baryon Asymmetry. Dissertation (Ph.D.), California Institute of Technology. doi:10.7907/7629-m351.


In part I of this thesis some of the parameters relevant to the production of a cosmological baryon number asymmetry are considered in the context of grand unified models. General expressions for the average baryon number generated in the free decays of bosons are derived . The CP violation necessary for the generation of a baryon excess is discussed for a variety of SU(5) models. The kinematics of baryon number production in an illustrative SO(10) model is discussed in detail. In part II a viable SO(10) model is constructed which reproduces the phenomenological fermion mass and mixing angle values. A detailed discussion of the beta function for this model is presented. This analysis includes the effects of scalars.
