Self-heating dark matter via semi-annihilation
Ayuki Kamada, Hee Jung Kim, Hyungjin Kim +1
The freeze-out of dark matter (DM) depends on the evolution of the DM temperature. The DM temperature does not have to follow the standard model one, when the elastic scattering is…
Axion-like particle assisted strongly interacting massive particle
Ayuki Kamada, Hyungjin Kim, Toyokazu Sekiguchi
We propose a new realization of strongly interacting massive particles (SIMP) as self-interacting dark matter, where SIMPs couple to the Standard Model sector through an axion-like…
Pulsar Timing Constraints on Physics Beyond the Standard Model
Niayesh Afshordi, Hyungjin Kim, Elliot Nelson
We argue that massive quantum fields source low-frequency long-wavelength metric fluctuations through the quantum fluctuations of their stress-energy, given reasonable assumptions…
