Effective theory for self-interacting dark matter and massive spin-2 mediators / Kang, Yoo-Jin (Chung-Ang U. ; CERN) ; Lee, Hyun Min (Chung-Ang U. ; CERN)
We consider the effective theory for self-interacting dark matter with arbitrary spin and go beyond the previous discussion in the literature by introducing a massive spin-2 particle as the mediator for the dark matter self-scattering. We present the effective self-interactions for dark matter in the leading order expansions with the momentum transfer and the dark matter velocity. [...]

Dark matter self-interactions from spin-2 mediators / Kang, Yoo-Jin (Chung-Ang U. ; CERN) ; Lee, Hyun Min (Chung-Ang U. ; CERN)
We propose a new mechanism for rendering dark matter self-interacting in the presence of a massive spin-2 mediator. The derived Yukawa-type potential for dark matter is independent of the spins of dark matter in the leading order of the momentum expansion, so are the resulting non-perturbative effects for the dark matter self-scattering. [...]

Lightening Gravity-Mediated Dark Matter / Kang, Yoo-Jin (Chung-Ang U. ; CERN) ; Lee, Hyun Min (CERN ; Chung-Ang U.)
We revisit the scenario of a massive spin-2 particle as the mediator for communicating between dark matter of arbitrary spin and the Standard Model. Taking the general couplings of the spin-2 particle in the effective theory, we discuss the thermal production mechanisms for dark matter with various channels and the dark matter self-scattering.

Connecting between inflation and dark matter in models with gauged Z$_{3}$ symmetry / Choi, Soo-Min (Chung-Ang U. ; CERN) ; Kim, Jinsu (Gottingen U.) ; Lee, Hyun Min (Chung-Ang U. ; CERN) ; Zhu, Bin (Chung-Ang U. ; Yantai U.)
We investigate the possibility of unifying the inflation and dark matter physics in the minimal model for a complex scalar dark matter with gauged $Z_3$ symmetry. The dark local $U(1)$ symmetry is broken spontaneously into the $Z_3$ symmetry by the dark Higgs mechanism. [...]

The Selfish Higgs and Reheating / Lee, Hyun Min (Chung-Ang U. ; CERN)
We consider the cosmological relaxation of the Higgs mass and the cosmological constant due to the four-form fluxes in four dimensions. We present a general class of models with a singlet scalar field containing four-form couplings where the Higgs mass is relaxed to a right value and the Universe reheats to a sufficiently high reheating temperature after the last membrane nucleation.

Exothermic Dark Matter for XENON1T Excess / Lee, Hyun Min (Chung-Ang U. ; CERN)
Motivated by the recent excess in the electron recoil from XENON1T experiment, we consider the possibility of exothermic dark matter, which is composed of two states with mass splitting. The heavier state down-scatters off the electron into the lighter state, making an appropriate recoil energy required for the Xenon excess even for the standard Maxwellian velocity distribution of dark matter.
