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…
