The leading effects of heavy new physics beyond the Standard Model can be parametrized model-independently through 59 dimension-6 operators, many of which can potentially affect Higgs Physics. I will separate these operators in different groups, constrained at different levels of precision by previous experiments (LEP, SLC, TeVatron), and show that only 8 can give an unconstrained contributions to Higgs observables.
