Production of top quarks, jets and photons

Measurements of the production of top quarks, jets and photons using the ATLAS and CMS detectors at the LHC are presented. Top quark results include the measurement of highly boosted $t\bar{t}$ pairs decaying exclusively to hadrons as well as differential cross sections in various decay channels whi...

description Measurements of the production of top quarks, jets and photons using the ATLAS and CMS detectors at the LHC are presented. Top quark results include the measurement of highly boosted $t\bar{t}$ pairs decaying exclusively to hadrons as well as differential cross sections in various decay channels which are, in some cases, used to determine the strong coupling constant and the mass of the top quark. Measurements of jet production probe both the perturbative and non-perturbative regime, including measurements of dijet and trijet production in the back-to-back limit as well as fragmentation, gluon splitting and event shape studies. Photon analyses include measurements of the inclusive photon and photon plus jet cross sections, as well as the ratio of the cross sections for the centre-of-mass energies of 13 TeV and 8 TeV.
