Radiative natural supersymmetry: Reconciling electroweak fine-tuning and the Higgs boson mass

H Baer, V Barger, P Huang, D Mickelson… - Physical Review D …, 2013 - APS
Models of natural supersymmetry seek to solve the little hierarchy problem by positing a
spectrum of light Higgsinos≲ 200–300 GeV and light top squarks≲ 600 GeV along with very …

Spread Supersymmetry with LSP: gluino and dark matter signals

LJ Hall, Y Nomura, S Shirai - Journal of High Energy Physics, 2013 - Springer
A bstract The discovery of a Higgs boson near 125 GeV, together with the absence of LHC
signals for supersymmetry or direct detection signals of dark matter, motivate further study of …

Post-LHC7 fine-tuning in the minimal supergravity/CMSSM model<? format?> with a 125 GeV Higgs boson

H Baer, V Barger, P Huang, D Mickelson… - Physical Review D …, 2013 - APS
The recent discovery of a 125 GeV Higgs-like resonance at LHC, coupled with the lack of
evidence for weak scale supersymmetry (SUSY), has severely constrained SUSY models …

Light neutralino dark matter: direct/indirect detection and collider searches

T Han, Z Liu, S Su - Journal of High Energy Physics, 2014 - Springer
A bstract We study the neutralino being the Lightest Supersymmetric Particle (LSP) as a cold
Dark Matter (DM) candidate with a mass less than 40 GeV in the framework of the Next-to …

Upper bounds on sparticle masses from naturalness or how to disprove weak scale supersymmetry

H Baer, V Barger, M Savoy - Physical Review D, 2016 - APS
While it is often stated that the notion of electroweak (EW) naturalness in supersymmetric
models is subjective, fuzzy and model dependent, here we argue the contrary: electroweak …

Muon g− 2 vs LHC in Supersymmetric Models

M Endo, K Hamaguchi, S Iwamoto… - Journal of High Energy …, 2014 - Springer
A bstract There is more than 3σ deviation between the experimental and theoretical results
of the muon g− 2. When interpreted in SUSY extensions of the SM, this anomaly suggests …
