Freeze-in Asymmetric Dark Matter with a Dual-Role Scalar: CP Violation and Symmetric-Component Depletion
S. Peyman Zakeri
We present a minimal, predictive scenario for asymmetric fermionic dark matter (DM) generated through freeze-in. The standard model (SM) is extended by a Dirac fermion that ser…

Asymmetric Two-Component Scalar FIMP Dark Matter
S. Peyman Zakeri
We propose a two-component asymmetric feebly interacting massive particle (FIMP) dark matter (DM) model in which both DM candidates are complex scalar fields. The model is an exten…
