Measurements of Z gamma + jets differential cross sections in pp collisions at CMS = 13 TeV with the ATLAS detector

Popis výsledku v původním jazyce

Differential cross-section measurements of Z production in association withhadronic jets are presented, using the full 139 fb−1 dataset of ps = 13 TeV proton–protoncollisions collected by the ATLAS detector during Run 2 of the LHC. Distributions aremeasured using events in which the Z boson decays leptonically and the photon is usuallyradiated from an initial-state quark. Measurements are made in both one and two observables,including those sensitive to the hard scattering in the event and others which probeadditional soft and collinear radiation. Different Standard Model predictions, from bothparton-shower Monte Carlo simulation and fixed-order QCD calculations, are comparedwith the measurements. In general, good agreement is observed between data and predictionsfrom MATRIX and MiNNLOPS, as well as next-to-leading-order predictions fromMadGraph5_aMC@NLO and Sherpa.
