SUMMARY:Higgs alignment and the top quark
DESCRIPTION:Featuring Ken Lane\, Boston University\nHosted by: David Sperka
	\n\nPart of the HEE Seminar Series.\n\nThere is a surprising connection bet
	ween the top quark and Higgs alignment in Gildener-Weinberg multi-Higgs dou
	blet models. Were it not for the top quark and its large mass\, the couplin
	g of the 125 GeV Higgs boson H to gauge bosons and fermions would be indist
	inguishable to those of the Standard Model Higgs. The top quark's coupling 
	to a single Higgs doublet breaks this perfect alignment in higher orders of
	 the Coleman-Weinberg loop expansion of the effective potential. But the ef
	fect is still small\, O((1%). Common experimental searches for 2HDM (H'\, A
	\, H+-) bosons are discussed\, including those for which no signal is acces
	sible and those which are promising -- but challenging.\nhttps://bostonu.zo
