Beyond a symmetry-restricted VEV ansatz: transverse stability of an special-subgroup vacuum
Hidetoshi Kawase
Extended Higgs sectors can realize multistage breaking chains in grand unified theories (GUTs), and the resulting intermediate gauge phases can be relevant to cosmological defects.…
Light Neutralino Dark Matter Scenario in Supersymmetric Four-Higgs Doublet Model
Hidetoshi Kawase
We examine a possibility to explain the signals of dark matter direct detection from DAMA and CoGeNT experiments, under the framework of supersymmetric extension of the standard mo…
Flavor structure of E6 GUT models
Hidetoshi Kawase, Nobuhiro Maekawa
It has been pointed out that in E6 grand unified theory with SU(2) family symmetry, the spontaneous CP violation can solve the supersymmetric CP problem. The scenario predicts V_{u…
Gauge-mediated supersymmetry breaking with generalized messenger sector at LHC
Hidetoshi Kawase, Nobuhiro Maekawa, Kazuki Sakurai
We consider the generalized gauge mediated supersymmetry breaking (GMSB) models with the messenger fields which do not form the complete multiplets of SU(5) GUT symmetry. Such a si…
