Electroweak effective operators and Higgs physics
Electroweak effective operators and Higgs physics
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 $\mathrm{\ensuremath{\Delta}}S$, $\mathrm{\ensuremath{\Delta}}T$, and $\mathrm{\ensuremath{\Delta}}U$ oblique parameters are sensitive to these contributions, and we pay particular attention to the role of renormalization when …
