SUMMARY:DISCRETE NON-ABELIAN SYMMETRIES BEYOND THE STANDARD MODEL\, Th
 esis Defense\, Ariel Rock\, Physics PhD Graduate Student
DESCRIPTION:Abstract:
\nThe use of symmetry has been fundamental in th
 e development of the Standard Model\, and we continue to be guided by 
 symmetric considerations in building BSM theories of supersymmetry bre
 aking and flavor. We analyze a minimal flavored gauge mediation model 
 of supersymmetry breaking in which the electroweak Higgs and messenger
  doublets mix as multiplets of a discrete non-Abelian symmetry given b
 y the group S3.  We show that in a specific limit\, sizable stop mixin
 g and flavor diagonal soft supersymmetry breaking parameters are achie
 ved. In most of the parameter space\, the masses of the colored superp
 artners are at most in the 5–6 TeV range. We show that couplings at 
 the renormalizable level do not lead to viable quark mixing parameters
 \, requiring the inclusion of higher-dimensional operators. As a concr
 ete exploration of this idea\, we show that the Cabibbo angle can be g
 enerated within this framework via such couplings and explore the scen
 ario’s phenomenological implications. In a separate direction\, we a
 lso explore the effects of correlations among observable parameters of
  neutrino mixing on predictions for the leptonic Dirac CP-violating ph
 ase. Focusing on a standard class of theoretical models of neutrino mi
 xing governed by discrete non-Abelian symmetries corrected by a single
  charged lepton rotation\, we show that we can guarantee a physically 
 meaningful prediction for the most likely value of the leptonic Dirac 
 CP-violating phase.
