Status of diboson production in NNLO QCD

TL;DR

This paper reports the first fully differential NNLO QCD calculations for ZZ diboson production, incorporating off-shell, decay, and non-resonant effects, and compares these predictions with experimental data from ATLAS and CMS at 8 and 13 TeV.

Contribution

It provides the first fully differential NNLO QCD predictions for ZZ production including off-shell and decay effects, enhancing theoretical precision.

Findings

Good agreement with ATLAS and CMS measurements at 8 TeV

First comparison with early 13 TeV data shows consistency

Improves understanding of ZZ production at high precision

Abstract

We present results from the first fully differential next-to-next-to leading order NNLO QCD computation of ZZ production, including off-shell effects, the leptonic decay and non-resonant contributions. We compare theoretical predictions to fiducial cross sections and distributions measured by ATLAS and CMS at 8 TeV and also perform a first comparison with early ATLAS measurements at 13 TeV.
