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…
Gamma-ray boxes from axion-mediated dark matter
Alejandro Ibarra, Hyun Min Lee, Sergio López Gehler +2
We compute the gamma-ray output of axion-mediated dark matter and derive the corresponding constraints set by recent data. In such scenarios the dark matter candidate is a Dirac fe…
Singlet Portal Extensions of the Standard Seesaw Models to a Dark Sector with Local Dark Symmetry
Seungwon Baek, P. Ko, Wan-Il Park
Assuming ({\it i}) the seesaw mechanism works for neutrino masses and mixings, ({\it ii}) dark matter is absolutely stable due to unbroken dark gauge symmetry, and ({\it i…
Hidden sector dark matter and Higgs physics
Seungwon Baek, Pyungwon Ko, Wand-Il Park +1
We consider a hidden sector dark matter, where a singlet fermion is a cold dark matter and a real singlet scalar boson is a messenger between the SM and the hidden sectors. Thi…
