High-E T isolated-photon plus jets production in pp collisions at s=8 TeV with the ATLAS detector

The dynamics of isolated-photon plus one-, two- and three-jet production in pp collisions at a centre-of-mass energy of 8 TeV are studied with the ATLAS detector at the LHC using a data set with an integrated luminosity of 20.2 fb −1 . Measurements of isolated-photon plus jets cross sections are pre...
