What do precision Higgs measurements buy us

Abstract: The exciting discovery of the Higgs boson finally gives us a chance to experimentally probe all of its unnatural and mysterious properties. At the forefront of questions is whether or not there is new physics beyond the Standard Model that explain these unnatural and mysterious properties. This talk examines the sensitivities of future precision Higgs measurements and electroweak observables in probing BSM physics. Using effective field theory--appropriate since precision measurements are indirect probes of new physics--we examine well-motivated test cases. One of these test cases is a tree-level example due to a singlet scalar field that enables 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.
