Two component pseudo-Nambu-Goldstone-boson dark matter
Riasat Sheikh, Takashi Toma, Koji Tsumura
We study a two-component pseudo-Nambu-Goldstone-boson (pNGB) dark matter (DM) model motivated by boosted dark matter (BDM). The model is based on a complex scalar field charged und…

Pseudo-Nambu-Goldstone-boson Dark Matter from Three Complex Scalars
Riasat Sheikh, Takashi Toma, Koji Tsumura
This study explores a dark matter model in which a pseudo-Nambu-Goldstone boson arises as a viable dark matter candidate from the spontaneous and soft breaking of global $\mathrm{U…
