Pseudo Nambu-Goldstone Boson DM with Linear Symmetry Breaking: Revisited
Jongkuk Kim, P. Ko
In this work, we revisit pseudo Nambu Goldstone boson (pNGB) DM model where global dark symmetry is spontaneously broken as well as explicitly with broken by with linear sym…

Axion-Mediated Inelastic Dark Matter
Kyu Jung Bae, Jongkuk Kim
We consider the axion-mediated scattering processes between dark matter (DM) and nucleus. Substantial contributions are made via the CP-odd gluonic current which induces the spin-d…

Non-thermal WIMPy Baryogenesis with Primordial Black Hole
Ki-Young Choi, Jongkuk Kim, Erdenebulgan Lkhagvadorj
We consider the possibility that the weakly interacting massive particles produced from the evaporation of primordial black hole can explain both the relic density of dark matter a…
