Nearly Degenerate Majorana Dark Matter and Its Self-Interactions in a Gauged Model
Kwei-Chou Yang
We propose a model of nearly degenerate Majorana dark matter (DM) in a gauged extension of the Standard Model. Spontaneous symmetry breaking generates a dominant…
Self-Interacting Forbidden Dark Matter under a Cannibally Co-Decaying Phase
Kwei-Chou Yang
In a usual dark matter (DM) model without a huge mass difference between the DM and lighter mediator, using the coupling strength suitable for having the correct relic density, the…
Freeze-out Forbidden Dark Matter in the Hidden Sector in the Mass Range from sub-GeV to TeV
Kwei-Chou Yang
Kinematically forbidden channels can set the freeze-out dark matter (DM) relic abundance. These channels are described by DM annihilations into heavier states, which vanish at zero…
Diffusion of Cosmic Antiprotons Generated throughout the Dark Matter Halo -- A Semi-Analytical Solution for a Linear Galactic Wind Model
Kwei-Chou Yang
The public GALPROP code gives a fully numerical solution for the spectrum of cosmic rays propagating through a linear Galactic wind directed outwards from the Galactic plane in the…
A Potentially Detectable Gamma-Ray Line in the Fermi Galactic Center Excess -- In Light of One-Step Cascade Annihilations of Secluded (Vector) Dark Matter via the Higgs Portal
Kwei-Chou Yang
We show the presence of a potentially detectable gamma-ray line in the Fermi Galactic center excess in light of the secluded (vector) dark matter (DM) model in which the hidden sca…
Thermodynamic Evolution of Secluded Vector Dark Matter: Conventional WIMPs and Nonconventional WIMPs
Kwei-Chou Yang
The secluded dark matter resides within a hidden sector and self-annihilates into lighter mediators which subsequently decay to the Standard Model (SM) particles. Depending on the…
