Abstract
We present a precise theoretical prediction for the signal-background interference process of gg(→ h∗) → ZZ, which is useful to constrain the Higgs boson decay width and to measure Higgs couplings to the SM particles. The approximate NNLO K-factor is in the range of 2.05 − 2.45 (1.85 − 2.25), depending on M ZZ , at the 8 (13) TeV LHC. And the soft gluon resummation can increase the approximate NNLO result by about 10% at both the 8 TeV and 13 TeV LHC. The theoretical uncertainties including the scale, uncalculated multi-loop amplitudes of the background and PDF+αs are roughly \( \mathcal{O}\left(10\%\right) \) at NNLL′. We also confirm that the approximate K-factors in the interference and the pure signal processes are the same.
