Parity: from strong CP problem to dark matter, neutrino masses and baryon asymmetry
Pei-Hong Gu
We show that in an SU(3)_c\times [SU(2)_L\times U(1)_Y]\times [SU(2)'_R\times U(1)'_Y] framework, the parity symmetry motivated by solving the strong CP problem without resorting t…
Multi-component dark matter with magnetic moments for Fermi-LAT gamma-ray line
Pei-Hong Gu
We propose a model of multi-component dark matter with magnetic moments to explain the 130 GeV gamma-ray line hinted by the Fermi-LAT data. Specifically, we consider a U(1)_X dark…
Natural Inflation and Flavor Mixing from Peccei-Quinn Symmetry Breaking
Pei-Hong Gu, Manfred Lindner
We propose a left-right symmetric model to simultaneously give natural inflation and flavor mixing from a Peccei-Quinn symmetry breaking at the Planck scale. Our model can be embed…
Double and Linear Seesaw from Left-Right and Peccei-Quinn Symmetry Breaking
Pei-Hong Gu
In the left-right symmetric models, we can take the left-right symmetry to be the charge-conjugation and then impose a global symmetry under which the left- and right-handed fermio…
Universal Seesaw from Left-Right and Peccei-Quinn Symmetry Breaking
Pei-Hong Gu, Manfred Lindner
To generate the lepton and quark masses in the left-right symmetric models, we can consider a universal seesaw scenario by integrating out heavy fermion singlets which have the Yuk…
Visible and Dark Matter Genesis and Cosmic Positron/Electron Excesses
Pei-Hong Gu, Utpal Sarkar, Xinmin Zhang
Dark and baryonic matter contribute comparable energy density to the present Universe. The dark matter may also be responsible for the cosmic positron/electron excesses. We connect…
