Interesting radiative patterns of neutrino mass in an SU(3)_C X SU(3)_L X U(1)_X model with right-handed neutrinos
Darwin Chang, Hoang Ngoc Long
We investigate a simple model of neutrino mass based on SU(3)_C X SU(3)_L X U(1)_X gauge unification. The Yukawa coupling of the model has automatic lepton-number symmetry which is…
Generalized Study with Isospin-phased Topological Approach on the Puzzle
D. Chang, C. S. Chen, H. Hatanaka +1
We study the decay processes by using generalized decay amplitudes with both the final state re-scattering strong phases and the topological quark diagrammatic strong p…
Electric Dipole Moment in the Split Supersymmetry Models
Darwin Chang, We-Fu Chang, Wai-Yee Keung
We study an important contribution to the electric dipole moment (EDM) of the electron (or quarks) at the two-loop level due to the -EDM in the recently proposed scenario of spl…
Perturbative SO(10) Grand Unification
Darwin Chang, Takeshi Fukuyama, Yong-Yeon Keum +2
We consider a phenomenologically viable SO(10) grand unification model of the unification scale around GeV which reproduces the MSSM at low energy and allows pertu…
A model of CP Violation from Extra Dimension
Darwin Chang, Chian-Shu Chen, Chung-Hsien Chou +1
We construct a realistic model of CP violation in which CP is broken in the process of dimensional reduction and orbifold compactification from a five dimensional theories with $SU…
Natural Kobayashi-Maskawa Model of CP Violation and Flavor Physics
Darwin Chang, Wai-Yee Keung
We explore the possible tie between the naturalness of having a very small strong CP parameter in the Kobayashi-Maskawa Model and the flavor symmetry. We provide many examples…
