Journal of High Energy Physics Aims and scope Submit manuscript

Abstract

Interference between the Standard Model Higgs boson and continuum contributions in gg → ZZ is considered in the heavy-mass scenario. Results are available at leading order for the background (the gg → ZZ box diagrams). It is discussed how to combine the result with the next-to-next-to-leading order Higgs production cross-section and a proposal for estimating the associated theoretical uncertainty is presented.
