Hidden Sector Dark Matter with Global -symmetry and Fermi-LAT 130 GeV -ray Excess
Seungwon Baek, Hiroshi Okada
We suggest a dark matter scenario which could contribute the possible anomaly observed by Fermi-LAT -ray space telescope. It is based on the model recently proposed by Weinberg.…
Two Loop Neutrino Model and Dark Matter Particles with Global Symmetry
Seungwon Baek, Hiroshi Okada, Takashi Toma
We study a two loop induced seesaw model with global symmetry, in which we consider two component dark matter particles. The dark matter properties are investigated to…
Hidden sector monopole, vector dark matter and dark radiation with Higgs portal
Seungwon Baek, P. Ko, Wan-Il Park
We show that the 't Hooft-Polyakov monopole model in the hidden sector with Higgs portal interaction makes a viable dark matter model, where monopole and massive vector dark matter…
An alternative to the standard model
Seungwon Baek, Pyungwon Ko, Wan-Il Park
We present an extension of the standard model to dark sector with an unbroken local dark symmetry. Including various singlet portal interactions provided by the standard m…
Singlet portal extensions of the standard seesaw models to dark sector with local dark symmetry: An alternative to the new minimal standard model
S. Baek, P. Ko, Wan-Il Park
Assuming dark matter is absolutely stable due to unbroken dark gauge symmetry and singlet operators are portals to the dark sector, we present a simple extension of the standard se…
A dynamical CP source for CKM, PMNS and Leptogenesis
Y. H. Ahn, Seungwon Baek
We propose a simple model for the spontaneous CP violation based on symmetry for quarks and leptons in a seesaw framewor…
