Direct Detection and Cosmological Constraints of Dark Matter with Dark Dipoles
Takumi Kuwahara, Jun-Chen Wang, Shu-Run Yuan
We study a fermionic dark matter candidate that couples to the standard model particles exclusively through electric and magnetic dipole operators mediated by a massive dark photon…
Composite Asymmetric Dark Matter Assisted by Primordial Black Holes Evaporation
Takumi Kuwahara, Yoshiki Uchida
We investigate a cogenesis scenario for composite asymmetric dark matter framework: a dark sector has a similar strong dynamics to quantum chromodynamics in the standard model, and…
Revisiting Q-ball Interactions with Matters
Ayuki Kamada, Takumi Kuwahara, Keiichi Watanabe
Q-ball dark matter is one of the candidates for the macroscopic dark matter: Q-ball is a non-topological solitonic configuration, whose stability can be ensured by global charge an…
Composite asymmetric dark matter with a dark photon portal: Multimessenger tests
Saikat Das, Ayuki Kamada, Takumi Kuwahara +2
Composite asymmetric dark matter (ADM) is the framework that naturally explains the coincidence of the baryon density and the dark matter density of the Universe. Through a portal…
Mediator Decay through mixing with Degenerate Spectrum
Ayuki Kamada, Takumi Kuwahara, Shigeki Matsumoto +2
The decay of the mediator particle into standard model (SM) particles plays a significant role in exploring the dark sector scenario. We consider such a decay, taking the dark phot…
Quantum Theory of Dark Matter Scattering
Ayuki Kamada, Takumi Kuwahara, Ami Patel
Dark matter self-scattering is one of key ingredients for small-scale structure of the Universe, while dark matter annihilation is important for the indirect measurements. There is…
