ELKO dark matter from freeze-in

Key Points

The research aims to determine the coupling constants necessary for ELKO dark matter production through freeze-in interactions.
Calculated coupling constants between ELKO and the Higgs field
Examined the ELKO-Higgs Yukawa coupling
Analyzed the conditions for freeze-in dark matter production
Identified extremely small couplings sufficient for ELKO dark matter
Established a theoretical framework for the interaction with the Higgs field

Abstract

We calculate coupling constants between ELKO and the Higgs field for the ELKO-Higgs Yukawa coupling, from the requirement to produce ELKO dark matter through freeze-in. We find that extremely small couplings suffice to produce ELKO dark matter through this mechanism.
