A top-squark hunter's guide
Howard Baer, Vernon Barger, Natsumi Nagata +1
In supersymmetric models with radiatively-driven naturalness and light higgsinos, the top squarks may lie in the 0.5- 3TeV range and thus only a fraction of natural parameter space…
Asymmetric Dark Matter Models in SO(10)
Natsumi Nagata, Keith A. Olive, Jiaming Zheng
We systematically study the possibilities for asymmetric dark matter in the context of non-supersymmetric SO(10) models of grand unification. Dark matter stability in SO(10) is gua…
Starobinsky-Like Inflation and Neutrino Masses in a No-Scale SO(10) Model
John Ellis, Marcos A. G. Garcia, Natsumi Nagata +2
Using a no-scale supergravity framework, we construct an SO(10) model that makes predictions for cosmic microwave background observables similar to those of the Starobinsky model o…
The Super-GUT CMSSM Revisited
John Ellis, Jason L. Evans, Azar Mustafayev +2
We revisit minimal supersymmetric SU(5) grand unification (GUT) models in which the soft supersymmetry-breaking parameters of the minimal supersymmetric Standard Model (MSSM) are u…
Probing gaugino coannihilation with displaced vertex searches
Natsumi Nagata
Bino-like dark matter in supersymmetric theories tends to suffer from over-production. This problem can be evaded if there is another gaugino which has a mass close to the bino mas…
Precision gaugino mass measurements as a probe of large trilinear soft terms at ILC
Kyu Jung Bae, Howard Baer, Natsumi Nagata +1
In supersymmetric models with radiatively-driven naturalness, higgsino-like electroweak-inos (EW-inos) are expected to lie in a mass range 100--300 GeV, the lighter the more natura…
