Yukawa Quasi - Unification
We construct concrete supersymmetric grand unified theories based on the Pati-Salam gauge group SU (4) c × SU (2) L × SU (2) R which naturally lead to a moderate violation of 'asymptotic' Yukawa unification and thus can allow an acceptable b-quark mass even with universal boundary conditions. We consider the constrained minimal supersymmetric standard model which emerges from one of these theor...
متن کاملMSSM with Yukawa Quasi-Unification
We consider the constrained minimal supersymmetric standard model which emerges from one theory with a small deviation from Yukawa unification which is adequate for μ > 0. We show that this model possesses a wide and natural range of parameters which is consistent with the data on b → sγ, the muon anomalous magnetic moment, the cold dark matter abundance in the universe, and the Higgs boson mas...
متن کاملYukawa Quasi-unification and Neutralino Relic Density
The construction of a Supersymmetric Grand Unified Model based on the Pati-Salam gauge group is briefly reviewed and the low energy consequences of the derived asymptotic Yukawa quasi-unification conditions are examined. In the framework of the resulting Constrained Minimal Supersymmetric Standard Model, the cosmological relic density of the bino-like LSP is calculated and the results are expli...
متن کاملUnification Beyond GUTs : Gauge - Yukawa Unification ∗
Gauge-Yukawa Unification (GYU) is a renormalization group invariant functional relation among gauge and Yukawa couplings which holds beyond the unification point in Grand Unified Theories (GUTs). We present here various models where GYU is obtained by requiring the principles of finiteness and reduction of couplings. We examine the consequences of these requirements for the low energy parameter...
متن کاملTest of Gauge-Yukawa Unification
Recently it has been proposed that, in the framework of quantum field theory, both the Standard Model gauge and Yukawa interactions arise from a single gauge interaction in higher dimensions with supersymmetry. This leads to the unification of the Standard Model gauge couplings and the third family Yukawa couplings at the GUT scale. In this work, we make a detailed study of this unification usi...
