Neutrino Masses, Leptogenesis and Decaying Dark Matter

Chuan-Hung Chen, Chao-Qiang Geng, Dmitry V. Zhuridov

We study a simple extension of the standard model to simultaneously explain neutrino masses, dark matter and the matter-antimatter asymmetry of the Universe. In our model, the bary…

Leptogenesis in a model with Friedberg-Lee symmetry

Takeshi Araki, C. Q. Geng

We study the matter-antimatter asymmetry through the leptogenesis mechanism in a specific model with the Friedberg-Lee (FL) symmetry.We relate the leptogenesis with the CP violatin…

Resolving Fermi, PAMELA and ATIC anomalies in split supersymmetry without R-parity

Chuan-Hung Chen, Chao-Qiang Geng, Dmitry V. Zhuridov

A long-lived decaying dark matter as a resolution to Fermi, PAMELA and ATIC anomalies is investigated in the framework of split supersymmetry (SUSY) without R-parity, where the neu…

ATIC/PAMELA anomaly from fermionic decaying Dark Matter

Chuan-Hung Chen, Chao-Qiang Geng, Dmitry V. Zhuridov

We demonstrate that an economical two Higgs doublet model can explain the electron and positron excesses in the recent ATIC and PAMELA experiments by the three body decays of the d…

mixings and $b\to q (\ga, \ell \bar \ell)$ decays in private Higgs model

Rachid Benbrik, Chuan-Hung Chen, Chao-Qiang Geng

We study the low energy phenomena induced by the lightest charged Higgs in the private Higgs (PH) model, in which each quark flavor is associated with a Higgs doublet. We show that…
