SUMMARY:What do precision Higgs measurements buy us?
DESCRIPTION:Featuring Brian Henning\, UC Berkeley\n\nPart of the HET Semina
	r Series.\n\nAbstract:\nThe exciting discovery of the Higgs boson finally g
	ives us a chance to experimentally probe the strangest particle in the Stan
	dard Model. At the forefront of questions is whether or not there is new ph
	ysics beyond the Standard Model that explains the unnatural and mysterious 
	properties of the Higgs boson. In this talk\, we examine the sensitivities 
	of future precision Higgs measurements and electroweak observables in probi
	ng BSM physics. We argue that effective field theory (EFT) is the appropria
	te framework for future precision studies and develop several useful tools 
	for this study. In particular\, we present a manifestly gauge covariant met
	hod of calculating one-loop effective actions to determine Wilson coefficie
	nts in the EFT. We also provide a direct mapping between Wilson coefficient
	s and precision observables. Taken together\, these provide a useful dictio
	nary to easily translate between UV models and experimental parameters. Wit
	hin this EFT framework\, we examine well-motivated test cases. One of these
	 test cases is a tree-level example due to a singlet scalar field that enab
	les the first-order electroweak phase transition for baryogenesis. Another 
	is a one-loop example due to scalar top in the MSSM. We find both Higgs and
	 electroweak measurements are sensitive probes of these cases.
