Model Building by Coset Space Dimensional Reduction Scheme Using Twelve-Dimensional Coset Spaces
Kento Asai, Joe Sato, Ryosuke Suda +2
We investigate the twelve-dimensional gauge-Higgs unification models with an eight-dimensional coset space. For each model, we apply the coset space dimensional reduction procedure…
Asymmetric Mediator in Scotogenic Model
Kento Asai, Yuhei Sakai, Joe Sato +2
The scotogenic model is the Standard Model (SM) with Z_2 symmetry and the addition of Z_2 odd right-handed Majorana neutrinos and SU(2)_L doublet scalar fields. We have extended th…
Sensitivity of indirect detection of Neutralino dark matter by Sommerfeld enhancement mechanism
Mikuru Nagayama, Joe Sato, Yasutaka Takanishi +1
We have investigated neutralino dark matter in the framework of minimal supersymmetric Standard Model focusing on the coannihilatioin region. In this region, where the particle who…
Big-bang nucleosynthesis and Leptogenesis in CMSSM
Munehiro Kubo, Joe Sato, Takashi Shimomura +2
We have investigated the constrained minimal supersymmetric standard model with three right-handed Majorana neutrinos whether there still is a parameter region which is consistent…
LHC Tests of Light Neutralino Dark Matter without Light Sfermions
Lorenzo Calibbi, Jonas M. Lindert, Toshihiko Ota +1
We address the question how light the lightest MSSM neutralino can be as dark matter candidate in a scenario where all supersymmetric scalar particles are heavy. The hypothesis tha…
A lower bound on light neutralino dark matter from LHC data
Lorenzo Calibbi, Jonas M. Lindert, Toshihiko Ota +1
Under the hypothesis that the MSSM neutralino accounts for the observed dark matter density, we investigate how light this particle is still allowed to be after the latest LHC data…
