Dirac gaugino from grand gauge-Higgs unification
Hiroaki Nakano, Masamichi Sato, Osamu Seto +1
We show that models of the Dirac gaugino can naturally be embedded into a kind of the grand unified theory (GUT), the grand gauge-Higgs unification (gGHU) model, with the gauge gro…
Next-to-minimal -symmetric model: Dirac gaugino, Higgs mass and invisible width
Hiroaki Nakano, Masaki Yoshikawa
We study a singlet extension of the minimal symmetric model, which shares nice properties of Dirac gauginos and -symmetric Higgs sector. At the same time, a superpotent…
Neutrino Mass and Proton Decay in a Symmetric Model
Yusuke Morita, Hiroaki Nakano, Takashi Shimomura
We study a symmetric extenstion of supersymmetric standard model with supersymmetry breaking in the visible as well as hidden sectors. Specifically we study b…
Soft Supersymmetry Breaking at Heavy Chiral Threshold
Hiroyuki Matsuura, Hiroaki Nakano, Koichi Yoshioka
We discuss the structure of threshold corrections to soft supersymmetry-breaking parameters at the mass threshold of heavy chiral superfields. Nontrivial dependence on soft paramet…
Induced top Yukawa coupling and suppressed Higgs mass parameters
Tatsuo Kobayashi, Hiroaki Nakano, Haruhiko Terao
In the scenarios with heavy top squarks, mass parameters of the Higgs field must be fine-tuned due to a large logarithmic correction to the soft scalar mass. We consider a new poss…
Large Mass Scale by Strong Gauge Dynamics with Infrared Fixed Point
Tatsuo Kobayashi, Hiroaki Nakano, Haruhiko Terao +1
We consider a mechanism for realizing the desired decoupling of strongly-coupled sector which is supposed to generate hierarchical structure of the Yukawa couplings. In our mechani…
