Mixing-induced CP asymmetry in B-> K* gamma decays with perturbative QCD approach
M. Matsumori, A. I. Sanda
The mixing-induced CP asymmetries in B-> K* gamma -> K_S pi^0 gamma and B-> K* gamma -> K_L pi^0 gamma are expected to be small within the standard model. So they are among the mos…
Nonabelian Discrete Family Symmetry to Soften the SUSY Flavor Problem and to Suppress Proton Decay
Yuji Kajiyama, Etsuko Itou, Jisuke Kubo
Family symmetry could explain large mixing of the atmospheric neutrinos. The same symmetry could explain why the flavor changing current processes in supersymmetric standard models…
Singlino dominated LSP as CDM candidate in supersymmetric models with an extra U(1)
Daijiro Suematsu
We consider a singlino dominated neutralino in supersymmetric models with an extra U(1). In case both the term and also the mass are generated by the vacuum expectat…
Nonthermal production of baryon and dark matter
Daijiro Suematsu
We study nonthermal production of baryon and dark matter. If we extend the MSSM by introducing some singlet chiral superfields so as to enlarge the conserved global symmetry, the a…
Dihedral Flavor Symmetry from Dimensional Deconstruction
Jisuke Kubo
Extra dimension deconstructed on a closed chain has naturally the symmetry of a regular polygon, the dihedral symmetry D_N. We assume that the fields are irreducible representation…
Neutrino texture saturating the CP asymmetry
Takayasu Baba, Daijiro Suematsu
We study a neutrino mass texture which can explain the neutrino oscillation data and also saturate the upper bound of the CP asymmetry in the leptogenesis. We consider the th…
S_3 Flavor Symmetry and Leptogenesis
Takeshi Araki, Jisuke Kubo, Emmanuel A. Paschos
We consider leptogenesis in a minimal S_3 extension of the standard model with an additional Z_2 symmetry in the leptonic sector. It is found that the CP phase appearing in the neu…
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…
