Description
Author and Presenter: Dipan Sengupta
Abstracts: Extra-dimensional models where Kaluza-Klein particles mediate interactions of a dark sector with the Standard Model particles have recently found a renewed interest. This talk will explore some deeper theoretical and phenomenological issues within these set-ups, both in the context of WIMP and FIMP dark matter models. I will demonstrate that self-consistency and relic density considerations severely constrain these models. Finally, I will talk about some cosmological consequences of these
models, including constraints from CMB and Lyman-alpha forest data.
