Proton Stability in S_4 x Z_2 Flavor Symmetric Extra U(1) Model
Yasuhiro Daikoku, Hiroshi Okada
We consider proton stability based on E_6 inspired extra U(1) model with S_4 x Z_2 flavor symmetry. In this model, a long life time of proton is realized by the flavor symmetry in…
Lepton Flavor Model and Decaying Dark Matter in The Binary Icosahedral Group Symmetry
Kenji Hashimoto, Hiroshi Okada
We propose a new flavor model that can simlutaneously well-describe the indirect detection experiment of (decaying) dark matter in the cosmic-ray, with the binary icosahedral group…
A light Scalar Dark Matter for CoGeNT and DAMA in D_6 Flavor Symmetric Model
Yuji Kajiyama, Hiroshi Okada, Takashi Toma
We try to interpret a very light dark matter with mass of 5~10 GeV which is in favor of the recent experiments reported by CoGeNT and DAMA, in a non-supersymmetric extension of rad…
Nonzero Theta13 for Neutrino Mixing in a Supersymmetric B-L Gauge Model with T_7 Lepton Flavor Symmetry
Qing-Hong Cao, Shaaban Khalil, Ernest Ma +1
We discuss how θ_{13} \neq 0 is accommodated in a recently proposed renormalizable model of neutrino mixing using the non-Abelian discrete symmetry T_7 in the context of a supersym…
Two Component Dark Matters in S_4 x Z_2 Flavor Symmetric Extra U(1) Model
Yasuhiro Daikoku, Hiroshi Okada, Takashi Toma
We study cosmic-ray anomaly observed by PAMELA based on E_6 inspired extra U(1) model with S_4 x Z_2 flavor symmetry. In our model, the lightest flavon has very long lifetime of O(…
Muon Anomalous Magnetic Moment and mu -> e gamma in B-L Model with Inverse Seesaw
W. Abdallah, A. Awad, S. Khalil +1
We study the anomalous magnetic moment of the muon, a_μ, and lepton flavor violating decay μ-> e γin TeV scale B-L extension of the Standard Model (SM) with inverse seesaw mechanis…
