Clockworking FIMPs

Understand

We study freeze-in dark matter production in models that rely on the Clockwork mechanism to suppress the dark matter couplings to the visible sector.

• We construct viable scalar and fermionic dark matter models within this Clockwork FIMP scenario, with several subtleties that need to be taken into account revealed in the model-building process.
• We also provide analytic, semi-analytic and numerical results for the diagonalization of Clockwork-type mass matrices and briefly discuss the LHC phenomenology of the corresponding scenarios.
