Description

We discuss effects of anomalous Higgs boson couplings characterized by dimension-six operators on the Higgs boson production and decay processes at the LHC and the ILC. The decay pattern of the Higgs boson and the production cross section of $gg\to H$, $e^{+}{e}^{-}\to t\overline{H}$, $e^{+}{e}^{-}\to ZHH$ and $e^{+}{e}^{-}\to \nu \overline{\nu }HH$ can receive large modifications from the anomalous dim-6 couplings under the constraint from currently available data. We also find that the double Higgs boson production $gg\to HH$ is very sensitive to the dimension-six top-Higgs operator. These effects can be detectable at future collider experiments.
