127. Dynamical Generation of Soft Supersymmetry Breaking Masses -- towards a viable model of dynamical electroweak symmetry breaking
Otto Kong (National Central University, Taiwan)
Simple dynamical electroweak symmetry breaking model via the NJL mechanism cannot be phenomenologically viable unless with supersymmetry. The supersymmetric case requires input soft supersymmetry breaking mass. To find a way to get to a model a good model witout any input masses, we constructed a simple model with supersymmetry itself dynamically broken by anothor NJL-type four-superfield...

Supersymmetric $E_6$ GUT models contain exotic vector-like quark superfields, which can influence the phenomenology of current and future precision experiments in flavour physics. We propose a minimal $E_6$ model with sufficiently light exotic (s)quarks without too rapid proton decay. I discuss the renormalization group evolution of the Yukawa sector and the experimental constraints from...

Flavour symmetries a la Froggatt-Nielsen provide a compelling way to explain the hierarchy of fermionic masses and mixing angles in the Yukawa sector. In Supersymmetric extensions of the SM where the breaking of Supersymmetry occurs at scales much larger than the breaking of flavour, this flavour symmetry must be respected not only by the Yukawas of the superpotential, but by the soft -...

We study the quark flavor violating Higgs-boson decay h->bs in the Minimal Supersymmetric Standard Model (MSSM). The decay is analyzed first in a model independent, and in a second step in the minimal flavor violationg (MFV) Constrained MSSM. The experimental constraints from $B$-Physics observables (BPO) and electroweak precision observables (EWPO) are also calculated and imposed on the...

We study SO(10), SU(5) and fipped SU(5) GUT models with non-universal soft supersymmetry-breaking scalar masses, exploring how they are constrained by LHC supersymmetry searches and cold dark matter experiments, and how they can be probed and distinguished in future experiments. We find characteristic differences between the various GUT scenarios, particularly in the coannihilation region,...
