Unified minimal supersymmetric model with large Yukawa couplings.
The consequences of assuming the third-generation Yukawa couplings are all large and comparable are studied in the context of the minimal supersymmetric extension of the standard model. General aspects of the RG evolution of the parameters, theoretical constraints needed to ensure proper electroweak symmetry breaking, and experimental and cosmological bounds on low-energy parameters are present...
متن کاملRadiative Fermion Mass Hierarchy in a Non-supersymmetric Unified Theory
In non-supersymmetric grand unified models a “radiative fermion mass hierarchy” can be achieved in which the spectrum of quark and lepton masses is determined entirely by physics at the unification scale, with many relations following from the unified gauge symmetry, and with the masses of the lightest family arising from loops. A simple, realistic, and predictive model of this kind is presente...
متن کاملSymmetry Breaking in Supersymmetric E6 Models
We study the electroweak and U(1) ′ symmetry breaking patterns in models with the particle content of supersymmetric E6, including standard model singlets S and exotic quarks D, D̄. Motivated by free fermionic string models, we do not require E6-type relations between Yukawa couplings. In particular, we assume that baryon and lepton numbers are conserved, so that the exotic quarks can be light. ...
متن کاملTesting Unified Supersymmetric Models
I define the Standard Supersymmetric Model (SSM) as the minimal supersymmetric extension of the Standard Model with gauge coupling unification and universal soft supersymmetry breaking at the unification scale. This well-defined model has a five-dimensional space of unknown parameters (m t , tan β, m 1/2 , m 0 , A). I outline the top-down and bottom-up methods of solving this model. Thresholds ...
متن کاملLepton flavor violation in a supersymmetric E6 type model
Lepton flavor violating processes are obtained from the mixings between the ordinary leptons and the exotic leptons in the E6 27 representation. The effects of these lepton mixings are, however, suppressed naturally because of the hierarchy of the charged lepton masses. In the supersymmetric model, significant effects of lepton flavor violation rather appear through the slepton mixings which ar...
