Cosmology of Inelastic Self-Interacting Dark Matter: Linear Evolution and Observational Constraints

Xin-Chen Duan, Yue-Lin Sming Tsai, Ziwei Wang

We study the linear cosmological evolution of inelastic self-interacting dark matter in a two-component dark sector with a small mass splitting, assuming thermal initial conditions…

Exploring sub-GeV dark matter via $s$ -wave, $p$ -wave, and resonance annihilation with CMB data

Yu-Ning Wang, Xin-Chen Duan, Tian-Peng Tang +2

We revisit constraints on sub-GeV dark matter (DM) annihilation via $s$ -wave, $p$ -wave, and resonance processes using current and future CMB data from Planck, FIRAS, and upcoming e…
