This article presents a new set of proton parton distribution functions, ATLASepWZVjet20, produced in an analysis at next-to-next-to-leading order in QCD. The new data sets considered are the measurements of W+W^+W+ and W−W^-W− boson and ZZZ boson production in association with jets in pppppp collisions at s=8 TeVsqrt{s} = 8~mathrm{TeV}s ​=8 TeV performed by the ATLAS experiment at the LHC with integrated luminosities of 20.2 fb−120.2~mathrm{fb}^{-1}20.2 fb−1 and 19.9 fb−119.9~mathrm{fb}^{-1}19.9 fb−1, respectively. The analysis also considers the ATLAS measurements of differential W±W^{pm}W± and ZZZ boson production at s=7 TeVsqrt{s} = 7~mathrm{TeV}s ​=7 TeV with an integrated luminosity of 4.6 fb−14.6~mathrm{fb}^{-1}4.6 fb−1 and deep-inelastic-scattering data from e±pe^{pm}pe±p collisions at the HERA accelerator.
