Search for extra gauge bosons in Little Higgs models at a linear collider
Gi-Chol Cho, Aya Omote
A generic feature of little Higgs models is presence of extra neutral gauge bosons. In the littlest Higgs model, the neutral extra gauge boson A_H is lightest among the extra parti…
'TeV Gamma-ray Crisis' and an Anisotropic Space Model
Gi-Chol Cho, Jun-ichi Kamoshita, Mariko Matsunaga +2
To solve the `TeV gamma crisis', we examine a model whose one spatial direction is discretized at a high energy scale. Assuming the standard extra-galactic IR photon distribution,…
Muon g-2 and Minimal Supersymmetric Standard Model
Gi-Chol Cho
The supersymmetric contribution to the muon g-2 is studied in light of the finalization of the LEP electroweak precision data. The recent precise measurement of the muon g-2 of E82…
Mixing Matrix of Quarks Having Natural Twisting in E_6 Grand Unified Model
Midori Obara, Gi-Chol Cho, Makiko Nagashima +1
Mass matrix of quarks is studied in the Supersymmetric Grand Unified Theory (GUT). The fundamental representation in which corresponds to one generation c…
Supersymmetry versus precision experiments revisited
Gi-Chol Cho
We study constraints on the Minimal Supersymmetric Standard Model from electroweak experiments. We find that the light sfermions always make the fit worse than the Standard Model,…
Constraints on the mSUGRA parameter space from electroweak precision data
G. C. Cho, K. Hagiwara, C. Kao +1
We place constraints on the parameter space of the minimal supergravity (SUGRA) inspired supersymmetric (SUSY) extension of the standard model (SM), i.e. the mSUGRA model, by study…
