We report on EPPS16, the first global analysis of nuclear parton distribution functions (nPDFs) to include LHC data. Also for the first time, a full flavour dependence of nPDFs is allowed. While the included Z and W data are found to have insufficient statistics to yield stringent constraints, the CMS 5.02 TeV proton–lead dijet data prove crucial in setting the shape of nuclear gluon modifications. With these and other observables being measured in proton–lead runs, we are experiencing a shift of nPDFs to the LHC precision era.
