We investigate the resummation effects with a jet veto, for W^\ifmmode±\else\textpm\fiZ and ZZ production at the LHC in soft-collinear effective theory, where the invariant mass distributions and the total cross sections with different jet veto pTveto and jet radius R are presented at next-to-next-to-leading-logarithmic order (NNLO). We also compare the NLO+NNLL resummation results with powheg+pythia, and the LO mode and NLO mode of madgraph5amc@nlo+pythia. Our results show that, in general, the jet-veto resummation can increase the jet-veto efficiencies compared with those generators. Finally, we compare the NLO+NNLL resummation predictions and the experimental data, and find that our results agree with the CMS data within 2\ensuremathσ C.L. at √(S)=8 TeV.
