Realistic model for SU(5) grand unification
Noriyuki Oshimo
A grand unified model based on SU(5) and supersymmetry is presented. Pairs of superfields belonging to 15 and 15* representations are newly introduced, while gauge coupling unifica…
Baryogenesis by Quantum Gravity
Ken-ji Hamada, Azusa Minamizaki, Akio Sugamoto
A novel mechanism of baryogenesis is proposed on the basis of the phase transition from the conformal invariant space-time to the Einstein space-time in quantum gravity. Strong-cou…
Can the Baryon Number Density and the Cosmological Constant be interrelated?
Azusa Minamizaki, Akio Sugamoto
A toy model is proposed in which the cosmological constant and the baryon number density of the universe are interrelated. The model combines the mechanism of Dimopoulos and Susski…
An Exotic Approach to Hadron Physics
Masako Bando, Yoko Fukase, Jonathan Shock +2
An exotic approach to hadrons is discussed. It is based on the recently developed open-closed string duality explicitly conjectured as the AdS/CFT correspondence. Mesons as well as…
Decay of Charged Higgs boson in a scenario of SUSY breaking inspired neutrino mass
Gi-Chol Cho, Satoru Kaneko, Aya Omote
In some class of supersymmetric models, small neutrino mass is given as a consequence of the supersymmetry (SUSY) breaking. Phenomenologically interesting features of this scenario…
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…
