Higgs Masses in the Minimal SUSY SO(10) GUT
Takeshi Fukuyama, Amon Ilakovac, Tatsuru Kikuchi +2
We explicitly show that minimal SUSY SO(10) Higgs-Higgsino mass matrices evaluated by various groups are mutually consistent and correct. We comment on the corresponding results of…
Perturbative SO(10) Grand Unification
Darwin Chang, Takeshi Fukuyama, Yong-Yeon Keum +2
We consider a phenomenologically viable SO(10) grand unification model of the unification scale around GeV which reproduces the MSSM at low energy and allows pertu…
The Effect of Extra Dimension on Dark Matter
Nobuchika Okada, Osamu Seto
We investigate the thermal relic density of a cold dark matter in the brane world cosmology. Since the expansion law in a high energy regime is modified from the one in the standar…
Decoupling Supersymmetry/Higgs without fine-tuning
Naoyuki Haba, Nobuchika Okada
We propose a simple superpotential for the Higgs doublets, where the electroweak symmetry is broken at the supersymmetric level. We show that, for a class of supersymmetry breaking…
Top Spin Correlations in Theories with Large Extra-Dimensions at the Large Hadron Collider
Masato Arai, Nobuchika Okada, Karel Smolek +1
In theories with large extra dimensions, we study the top spin correlations at the Large Hadron Collider. The s-channel process mediated by graviton Kaluza-Klein modes contributes…
Neutralino dark matter in brane world cosmology
Takeshi Nihei, Nobuchika Okada, Osamu Seto
The thermal relic density of the neutralino dark matter in the brane world cosmology is studied. Since the expansion law at a high energy regime in the brane world cosmology is mod…
