Abstract
We study freeze-in dark matter production in models that rely on the Clock-work 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.
