Description
We derive bounds from oblique parameters on the dimension-$6$ operators of an
effective field theory of electroweak gauge bosons and the Higgs doublet. The loop-
induced contributions to the $\Delta S$, $\Delta T$, and $\Delta U$ oblique parameters
are sensitive to these contributions and we pay particular attention to the role of
renormalization when computing loop corrections in the effective theory.
Limits on the coefficients of the effective theory from
loop contributions to oblique parameters yield complementary information to direct
Higgs production measurements.
