Higgs Interference Effects in $\text{Pg}\text{Pg}\to \text{PZ}\text{PZ}$ and their Uncertainty

Abstract

Interference between the Standard Model Higgs boson and continuum contributions is considered in the heavy-mass scenario. Results are available at leading order for the background. 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.
