Natural Supersymmetry and b -> s gamma constraints
Koji Ishiwata, Natsumi Nagata, Norimi Yokozaki
We investigate constraints from the observed branching ratio for b -> s gamma and fine-tuning in the framework of natural supersymmetry. The natural supersymmetry requires the larg…
Direct Detection of Dark Matter Degenerate with Colored Particles in Mass
Junji Hisano, Koji Ishiwata, Natsumi Nagata
In this Letter we explore the direct detection of the dark matter in the universe, assuming the dark matter particles are degenerate in mass with new colored particles below TeV sc…
Direct Detection of Electroweak-Interacting Dark Matter
Junji Hisano, Koji Ishiwata, Natsumi Nagata +1
Assuming that the lightest neutral component in an SU(2)L gauge multiplet is the main ingredient of dark matter in the universe, we calculate the elastic scattering cross section o…
