Pentaquark Baryons in String Theory -- Talk at Pentaquark 04
M. Bando, T. Kugo, A. Sugamoto +1
Pentaquark baryons and are studied in the dual gravity theory of QCD in which simple mass formulae of pentaquarks are derived in the Maldacena prototype model for…
An Attempt to Study Pentaquark Baryons in String Theory
Akio SUGAMOTO
An attempt to study recently observed Pentaquark baryons is performed in the dual string theory of QCD. Mass formulae for Pentaquark baryons are naively estimated in the Maldacena'…
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…
Baryon asymmetry and neutron EDM
Mayumi Aoki, Noriyuki Oshimo, Akio Sugamoto
Baryon asymmetry of the universe can be generated by new sources of violation intrinsic in supersymmetric extension of the standard model. This scenario predicts the neutron e…
Electroweak Baryogenesis and Neutron Electric Dipole Moment from Supersymmetry
Mayumi Aoki, Noriyuki Oshimo, Akio Sugamoto
Baryogenesis at the electroweak phase transition is discussed within the framework of the supersymmetric standard model. Implications of baryon asymmetry for the electric dipole mo…
Non-spectator contributions to B->X_s eta'
M. R. Ahmady, E. Kou, A. Sugamoto
We propose a nonspectator mechanism in which eta' is produced by two gluon fusion as the underlying process to explain the inclusive B-> X_s eta' as well as the exclusive B -> K^(*…
