IFAE Seminar Room (In-Person)

In this talk (based on  2407.20591), I will consider extensions of the Standard Model (SM) featuring vectorlike fermions charged under a new confining force, referred to as 'dark color.' These dark fermions condense to form a spectrum of dark hadrons, with the lightest accidentally stable dark baryon, with a mass of around 100 TeV, serving as a viable thermal dark matter candidate. I will, in particular, consider the grand unified theory (GUT) SU(5) framework for these models, highlighting how gauge coupling unification within the SM imposes stringent constraints on their construction. Additionally, I will discuss the unique cosmological scenarios these unified theories present and their phenomenological implications.
