SUMMARY:Cosmology and Astrophysics of the Twin Higgs
DESCRIPTION:Featuring David Curtin\, University of Toronto\nHosted by: Zeyn
	ep Demiragli\n\nPart of the HEE Seminar Series.\n\nThe Twin Higgs model is 
	an attractive solution to the little Hierarchy problem with top partners th
	at are neutral under SM gauge charges. The framework is consistent with the
	 null result of LHC colored top partner searches while offering many altern
	ative discovery channels. Depending on model details\, the phenomenology lo
	oks very different: either spectacular long-lived particle signals at colli
	ders\, or a plethora of unusual cosmological and astrophysical signatures v
	ia the existence of a predictive hidden sector. I will examine the latter p
	ossibility\, and describe how the asymmetrically reheated Mirror Twin Higgs
	 provides a predictive framework for a highly motivated and highly non-triv
	ial interacting dark sector\, with correlated signals in the CMB\, Large Sc
	ale Structure\, and direct detection searches\, as well as higgs precision 
	measurements at colliders. This provides a vivid example of the collider-co
	smology complementarity\, and motivates a variety of new astrophysical sear
	ches\, including the search for X-ray point sources from Mirror Stars\, tha
	t are motivated by the hierarchy problem.
