Extending the supersymmetric little hierarchy
Abstract/Contents
- Abstract
- Particle physics describes particles and their interactions at many energy scales, and different models can be characterized by the relationships between these scales. In a natural model, particle properties are insensitive to perturbations at higher energy scales, while in a tuned model particle properties are determined by delicate cancellations between processes even at energy scales separated by large hierarchies. Is our universe natural or tuned? The answer to this question can have dramatic consequences for the interpretation of fundamental theories and for our understanding of the inflationary birth of our universe. The discovery of a Standard Model-like Higgs Boson at the CERN Large Hadron Collider (LHC) has made concrete the possibility that our universe may be tuned. However, the observed particles of the Standard Model may still form part of a natural model if new particles and symmetries are present at energies observable at the LHC and future colliders. Supersymmetry is one possible extension of the Standard Model motivated by the idea of naturalness, but its minimal version is highly constrained by searches from the first run of the LHC. We describe extensions of the minimal supersymmetric model in which a little hierarchy between the masses of the new supersymmetric particles and the Standard Model particles is consistent with naturalness and current LHC searches. We also discuss the potential for discovering these models in the upcoming collisions at the upgraded LHC and future colliders.
