Abstract
A degenerate supersymmetric particle spectrum can escape constraints from flavor physics and at the same time evade limits from the direct searches. If such a spectrum is light enough, it can also account for the observed value of the anomalous magnetic moment of the muon. Inspired by this, we consider a scenario where all the soft terms have approximately a common mass scale while allowing for small splittings. We study this scenario considering the constraints from Higgs mass, various B meson decays and the dark matter relic density. We find that, with superpartners similar to 800 - 1000 GeV, it is still possible to escape the present limits from the first run of LHC and flavor physics and can account for muon g - 2 within 2 sigma.
Highlights
Low energy Supersymmetry (SUSY) has been considered as one of the most compelling solutions of the problem of naturalness of the electroweak scale
A very interesting possibility to evade the strong Large Hadron Collider (LHC) bounds on low energy SUSY is to consider all the sparticles nearly degenerate in masses
We review the implications of degenerate soft masses on the physical mass spectrum of Degenerate Minimal Supersymmetric Standard Model (DMSSM)
Summary
Low energy Supersymmetry (SUSY) has been considered as one of the most compelling solutions of the problem of naturalness of the electroweak scale. These models typically generate a widely spread SUSY mass spectrum that leads to experimentally detectable large visible or missing energies. A very interesting possibility to evade the strong LHC bounds on low energy SUSY is to consider all the sparticles nearly degenerate in masses.
