Prospects for Higgs- and Z-resonant Neutralino Dark Matter
Koichi Hamaguchi, Kazuya Ishikawa
In the minimal supersymmetric standard models, neutralino dark matter with mass of GeV and GeV can have the thermal relic abundance $Ω…
Towards a Scale Free Electroweak Baryogenesis
Kazuya Ishikawa, Teppei Kitahara, Masahiro Takimoto
We propose a new electroweak baryogenesis scenario in high-scale supersymmetric (SUSY) models. We consider a singlet extension of the minimal SUSY standard model introducing additi…
Singlino Resonant Dark Matter and 125 GeV Higgs Boson in High-Scale Supersymmetry
Kazuya Ishikawa, Teppei Kitahara, Masahiro Takimoto
We consider a singlino Dark Matter (DM) scenario in a singlet extension model of the Minimal Supersymmetric Standard Model, which is so-called the Nearly MSSM (nMSSM). We find that…
Reconstruction of Vector-like Top Partner from Fully Hadronic Final States
Motoi Endo, Koichi Hamaguchi, Kazuya Ishikawa +1
We investigate the potential to search for the vector-like top partner in fully hadronic final states at the LHC. An algorithm is developed that kinematically reconstructs the vect…
Gauge Mediation Models with Vectorlike Matters at the LHC
Motoi Endo, Koichi Hamaguchi, Kazuya Ishikawa +2
Gauge mediation model with vectorlike matters (V-GMSB) is one of the few viable SUSY models that explains the 126 GeV Higgs boson mass and the muon anomalous magnetic moment simult…
