`Freeze-in production of FIMP dark matter'

Abstract: I will present an alternate, calculable mechanism of dark 
matter genesis, "thermal freeze-in", involving a Feebly Interacting 
Massive Particle (FIMP) interacting so feebly with the thermal bath 
that it never attains thermal equilibrium. As with the conventional 
"thermal freeze-out" production mechanism, the relic abundance reflects 
a combination of initial thermal distributions together with particle 
masses and couplings that can be measured in the laboratory or 
astrophysically. I will also talk about the possibility of asymmetric 
freeze-in the mechanism could be used to explain the observed link 
between the dark matter density and the baryon density, and is 
potentially fully testable by a combination of collider experiments 
and precision tests.
