Gauge coupling unification with extra Higgs doublets
Junpei Harada
Gauge coupling unification is studied within the framework where there are extra Higgs doublets and exotic fields. Supersymmetric models and nonsupersymmetric models are inve…
Neutrino mixing and CP violation from Dirac-Majorana mixing
Junpei Harada
We consider a minimal condition that predicts the 1-3 lepton mixing angle with the Cabibbo angle, and give the improved prediction of…
Non-maximal θ_{23}, large θ_{13} and tri-bimaximal θ_{12} via quark-lepton complementarity at next-to-leading order
Junpei Harada
We show that the next-to-leading order corrections in the quark-lepton complementarity are important to explain the observed pattern of neutrino mixing. In particular, the next-to-…
Neutrino mixing and CP violation from Dirac-Majorana bimaximal mixture and quark-lepton unification
Junpei Harada
We demonstrate that only two ansatz can produce the features of the neutrino mixing angles. The first ansatz comes from the quark-lepton grand unification; i…
Hypercharge and baryon minus lepton number in E6
J. Harada
We study assignments of the hypercharge and baryon minus lepton number for particles in the grand unification model. It is shown that there are three assignments of hyperchar…
Phenomenological approach to symmetry breaking pattern of democratic mass matrix
Junpei Harada
We investigate the symmetry breaking pattern of the democratic mass matrix model, which leads to the small flavor mixing in quark sector and bi-large mixing in lepton sector. We pr…
