In this the ory\, the dark to visible baryon masses are fixed by the ratio of dark to visible confinement scales\, which are determined to be nearby in mass thr ough the unification of the dark and visible gauge theories at a high scal e. Together with a mechanism for darko-baryo-genesis\, which arises natura lly from the grand unification sector\, the mass densities of the two sect ors must be nearby\, explaining the observed mass density of dark matter. We focus on the simplest possible example of such a theory\, where Standar d Model color SU(3)c is unified with dark color SU(2)D into SU(5) at an in termediate scale of around 10^8 -10^9 GeV. The dark baryon consists of two dark quarks in an isotriplet configuration. There are a range of importan t cosmological\, astrophysical and collider signatures to explore\, includ ing dark matter self-interactions\, early matter domination from the dark hadrons\, gravitational wave signatures from the hidden sector phase trans ition\, contributions to flavor observables\, as well as Hidden Valley-lik e signatures at colliders.\n LOCATION:https://researchseminars.org/talk/nhetc/32/ END:VEVENT END:VCALENDAR
