Precision axion physics with running axion couplings
Kiwoon Choi, Sang Hui Im, Hee Jung Kim +1
We study the renormalization group running of axion couplings while taking into account that the Standard Model can be extended to its supersymmetric extension at a certain energy…
Maximally self-interacting dark matter: models and predictions
Ayuki Kamada, Hee Jung Kim, Takumi Kuwahara
We study self-interacting dark matter (SIDM) scenarios, where the -wave self-scattering cross section almost saturates the Unitarity bound. Such self-scattering cross sections a…
Escalating core formation with dark matter self-heating
Ayuki Kamada, Hee Jung Kim
Exothermic scatterings of dark matter (DM) produce DM particles with significant kick velocities inside DM halos. In collaboration with DM self-interaction, the excess kinetic ener…
Decaying axinolike dark matter: Discriminative solution to small-scale issues
Kyu Jung Bae, Ayuki Kamada, Hee Jung Kim
The latest Lyman- forest data severely constrain the conventional warm dark matter solution to small-scale issues in the cold dark matter paradigm. It has been also reported tha…
Self-heating of Strongly Interacting Massive Particles
Ayuki Kamada, Hee Jung Kim, Hyungjin Kim
It was recently pointed out that semi-annihilating dark matter (DM) may experience a novel temperature evolution dubbed as self-heating. Exothermic semi-annihilation converts the D…
