Little Supersymmetry and the Supersymmetric Little Hierarchy Problem
The current experimental lower bound on the Higgs mass significantly restricts the allowed parameter space in most realistic supersymmetric models, with the consequence that these models exhibit significant fine-tuning. We propose a solution to this ‘supersymmetric little hierarchy problem’. We consider scenarios where the stop masses are relatively heavy in the 500 GeV to a TeV range. Radiativ...

متن کاملTeV Symmetry and the Little Hierarchy Problem
Constraints from precision electroweak measurements reveal no evidence for new physics up to 5 – 7 TeV, whereas naturalness requires new particles at around 1 TeV to address the stability of the electroweak scale. We show that this “little hierarchy problem” can be cured by introducing a symmetry for new particles at the TeV scale. As an example, we construct a little Higgs model with this new ...
متن کاملAdS/CFT and the Little Hierarchy Problem
The AdS/CFT correspondence is applied to a close analogue of the little hierarchy problem in AdSd+1, d ≥ 3. The new mechanism requires a Maxwell field that gauges a U(1)R symmetry in a bulk supergravity theory with a negative cosmological constant. Supersymmetry is explicitly broken by a non-local boundary term with dimensionless coupling h. Non-locality appears to cause no pathology, and the S...
متن کاملLandscape of Little Hierarchy
We investigate the little hierarchy between Z boson mass and the SUSY breaking scale in the context of landscape of electroweak symmetry breaking vacua. We consider the radiative symmetry breaking and found that the scale where the electroweak symmetry breaking conditions are satisfied and the average stop mass scale is preferred to be very close to each other in spite of the fact that their or...
