Gluon fusion contribution to HBB (B = H,γ, Z) at the LHC
Abstract
We have calculated one-loop amplitudes for the production of Higgs boson in association with two electroweak bosons (H,γ,Z) via gluon-gluon fusion. We present preliminary results for the total cross section at 8, 13 and 100 TeV center-of-mass energies at pp 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.
