One of the drivers for this seminar series is to get a glimpse of the many research questions, ideas, and results linked to the activities in our division. The seminars are intended to be very informal and we make plenty of room for questions and discussions.

Abstract: In this seminar, we will explore the invisible decay of the Higgs boson in the context of dark matter production via freeze-in at stronger coupling. Unlike traditional freeze-in models, where the dark matter coupling to the visible sector is extremely feeble, we investigate a regime where a sizable coupling is allowed without leading to thermalization. We will discuss the production of scalar and fermionic dark matter from the Standard Model thermal bath, considering the contribution of hadronic states at temperatures below the QCD scale. We will also address experimental constraints from the LHC and the prospects for detection at the HL-LHC and FCC, highlighting the relevance of invisible Higgs decay as a window into physics beyond the Standard Model.
