Abstract
We have calculated one-loop amplitudes for the production of Higgs boson in association with two electroweak bosons () via gluon-gluon fusion. We present preliminary results for the total cross section at 8, 13 and 100 TeV center-of-mass energies at colliders. We study the interference effect and, also comment on the effect of new physics in terms of anomalous couplings of the Higgs boson in these processes.
