# $ZZ$ production at the LHC: Fiducial cross sections and distributions in NNLO QCD

Grazzini, Massimiliano; Kallweit, Stefan; Rathlev, Dirk (2015). $ZZ$ production at the LHC: Fiducial cross sections and distributions in NNLO QCD. Physics Letters B, 750:407-410.

## Abstract

We consider QCD radiative corrections to the production of four charged leptons in the ZZ signal region at the LHC. We report on the complete calculation of the next-to-next-to-leading order (NNLO) corrections to this process in QCD perturbation theory. Numerical results are presented for $\sqrt{s}=8$ TeV, using typical selection cuts applied by the ATLAS and CMS collaborations. The NNLO corrections increase the NLO fiducial cross section by about $15\%$, and they have a relatively small impact on the shape of the considered kinematical distributions. In the case of the $\Delta\Phi$ distribution of the two Z candidates, the NNLO corrections improve the agreement of the theoretical prediction with the CMS data.
