Bosonic dark matter in a coherent state driven by thermal fermions
arXiv:2109.07423 · doi:10.1016/j.physletb.2022.136880
Abstract
If there is a scalar boson field interacting dominantly with a quark or a lepton in the thermal background, its coherent oscillation can be generated through the thermal effect and becomes a good dark matter candidate in a wide range of the coupling and masses. We describe the general features of this mechanism and analyze how it works in various situations considering asymptotic limits where analytic solutions can be obtained.
