Abstract

We study the anomalous coupling of Higgs bosons with the neutral gauge boson Z and γ in the context of an effective theory with six dimension invariant operators under SU (2) ⊗ U (1) symmetry. We find bounds for the fWW /Λ2 , f BB/Λ2 , f BW/Λ2 and fΦ, 1 /Λ2 parameters using the experimental results. We also consider deviations from the Standard Model due to new physics application to the processes decay H → γγ, H → γ Z.
