Dark Matter as the Z_2 Partner of the Standard Model Higgs Boson
Yasunori Nomura
A possible gamma-ray excess from the Galactic halo favors dark matter with a mass of several hundred GeV. In previous work, we found that an electroweak scalar doublet is a particu…

Electroweak Doublet Dark Matter for a Galactic Halo Gamma-Ray Excess
Yasunori Nomura, Tomonori Totani
Weakly interacting massive particles provide a well-motivated framework for dark matter, naturally reproducing the observed relic abundance through thermal freeze-out. A recent cla…

A Minimally Fine-Tuned Supersymmetric Standard Model
Z. Chacko, Yasunori Nomura, David Tucker-Smith
We construct supersymmetric theories in which the correct scale for electroweak symmetry breaking is obtained without significant fine-tuning. We calculate the fine-tuning paramete…
