Muon Anomalous Magnetic Moment and Lepton Flavor Violating Tau Decay in Unparticle Physics
Andi Hektor, Yuji Kajiyama, Kristjan Kannike
We study effects of unparticle physics on muon g-2 and LFV tau decay processes. LFV interactions between the Standard Model sector and unparticles can explain the difference of exp…
Lepton Flavor Violating tau decay by R-Parity Violation in a Family Symmetry
Yuji Kajiyama
In this talk, we investigate Lepton Flavor Violating (LFV) tau decay by R-Parity Violating (RPV) operators controlled by a non-Abelian discrete family symmetry. We assume tha…
The golden ratio prediction for the solar neutrino mixing
Yuji Kajiyama, Martti Raidal, Alessandro Strumia
We present a simple texture that predicts the cotangent of the solar neutrino mixing angle to be equal to the golden ratio. This prediction is 1.4 standard deviations below the pre…
The SUSY Flavor Problem, Proton Decay and Discrete Family Symmetry
Etsuko Itou, Yuji Kajiyama, Jisuke Kubo
We consider a supersymmetric extension of the standard model, which possess a family symmetry based on a binary dihedral group Q6, and investigate the consequences of the family sy…
D6 Family Symmetry and Cold Dark Matter at LHC
Yuji Kajiyama, Jisuke Kubo, Hiroshi Okada
We consider a non-supersymmetric extension of the standard model with a family symmetry based on D6 Z2 Z2, where one of Z2's is exactly conserved. This Z2 forbids the tree-level ne…
Nonabelian Discrete Family Symmetry to Soften the SUSY Flavor Problem and to Suppress Proton Decay
Yuji Kajiyama, Etsuko Itou, Jisuke Kubo
Family symmetry could explain large mixing of the atmospheric neutrinos. The same symmetry could explain why the flavor changing current processes in supersymmetric standard models…
