Description
I will explore two different scenarios to account for the
long lifetime of dark matter. In the first one, I will assume that
dark matter is stable when coupled to the SM but can proceed through
(non-minimal) interactions to gravity. Based on current observations,
I will show that even this 'gravitational portal' to dark matter decay
is rather constrained. In the second scenario, I will present an
extension of the SM where the dark matter candidate can be absolutely
stable without the aid of ad hoc additional symmetries.
