Natural Little Hierarchy from a Partially Goldstone Twin Higgs
Z. Chacko, Yasunori Nomura, Michele Papucci +1
We construct a simple theory in which the fine-tuning of the standard model is significantly reduced. Radiative corrections to the quadratic part of the scalar potential are constr…
Dark Matter before the LHC in a Natural Supersymmetric Standard Model
Ryuichiro Kitano, Yasunori Nomura
We show that the solid lower bound of about 10^{-44} cm^2 is obtained for the cross section between the supersymmetric dark matter and nucleon in a theory in which the supersymmetr…
A Solution to the Supersymmetric Fine-Tuning Problem within the MSSM
Ryuichiro Kitano, Yasunori Nomura
Weak scale supersymmetry has a generic problem of fine-tuning in reproducing the correct scale for electroweak symmetry breaking. The problem is particularly severe in the minimal…
(mu B)-driven Electroweak Symmetry Breaking
Yasunori Nomura, David Poland, Brock Tweedie
We consider a scenario in which the dominant quartic coupling for the Higgs doublets arises from the F-term potential, rather than the conventional SU(2)_L x U(1)_Y D-term potentia…
Minimally Fine-Tuned Supersymmetric Standard Models with Intermediate-Scale Supersymmetry Breaking
Yasunori Nomura, David Poland, Brock Tweedie
We construct realistic supersymmetric theories in which the correct scale for electroweak symmetry breaking is obtained without significant fine-tuning. We consider two classes of…
The Supersymmetric Fine-Tuning Problem and TeV-Scale Exotic Scalars
Yasunori Nomura, Brock Tweedie
A general framework is presented for supersymmetric theories that do not suffer from fine-tuning in electroweak symmetry breaking. Supersymmetry is dynamically broken at a scale Λ\…
