PineAPPL: NLO EW corrections for PDF processes

Modern parton distribution function (PDF) determinations either neglect higher-order corrections in the electroweak (EW) coupling or implement them approximately for a subset of PDF processes. We present new tool, PineAPPL, which supports perturbative correction arbitrary powers EW and strong constant, stores theoretical predictions independently used PDFs so-called interpolation grids. These are foundation any determination, will allow us to perform fit taking into account all processes consistently. Apart from PineAPPL can also be precision phenomenology study impact different choices sets, without rerunning time-consuming computation. As an application this tool we show Drell-Yan (DY) lepton-pair production were larger effects NLO seen that potentially influence comment about observables particularly suited not.
