Parallel Session Thursday: Dark Matter Session

Models of feebly-interacting Dark Matter (DM) have gained popularity due to the non-observation of DM in direct detection experiments. Unlike DM freeze-out, which occurs when the dark sector particles are non-relativistic, feebly-interacting DM is primarily produced at temperatures corresponding to the heaviest mass scale involved in the production process. As a result, quantum and finite...
We consider inflationary models with multiple spectator axions that couple to Abelian
(and non-Abelian) dark gauge sectors. We demonstrate two distinctive phenomena that
make this class of models attractive – first, the gravitational wave peak produced by
axions coupled to dark Abelian sectors can coherently sum, leading to an enhanced
signal. Second, we show that separation of the...
Although the Standard Model is very successful, there are still open
problems which it cannot explain, one of it being dark matter (DM).
This has led to various Beyond Standard Model theories, of which Two
Higgs Doublet models are very popular, as they are one of the simplest
extensions and lead to a rich phenomenology. Further extensions with
a complex singlet lead to a natural DM...
