A natural Little Hierarchy for SUSY from radiative breaking of PQ symmetry
Kyu Jung Bae, Howard Baer, Hasan Serce
While LHC8 Higgs mass and sparticle search constraints favor a multi-TeV value of gravitino mass m_{3/2}, electroweak naturalness favors a superpotential higgsino mass μ~100-200 Ge…
Mixed axion/gravitino dark matter from SUSY models with heavy axinos
Kyu Jung Bae, Howard Baer, Eung Jin Chun +1
We examine dark matter production rates in supersymmetric axion models typified by the mass hierarchy m_gravitino << m_neutralino << m_axino. In such models, one expects the dark m…
Implications of naturalness for the heavy Higgs bosons of supersymmetry
Kyu Jung Bae, Howard Baer, Vernon Barger +2
Recently, it has been argued that various measures of SUSY naturalness-- electroweak, Higgs mass and EENZ/BG-- when applied consistently concur with one another and make very speci…
Coupled Boltzmann computation of mixed axion neutralino dark matter in the SUSY DFSZ axion model
Kyu Jung Bae, Howard Baer, Andre Lessa +1
The supersymmetrized DFSZ axion model is highly motivated not only because it offers solutions to both the gauge hierarchy and strong CP problems, but also because it provides a so…
