Description

The dynamics of isolated-photon plus jet production in pp collisions at sqrt(s) = 13 TeV were studied with the ATLAS detector at the LHC using a dataset with an integrated luminosity of 3.2 /fb. The photons were reconstructed for photon transverse energies larger than 125 GeV. The jets were identified using the anti-kt algorithm with radius parameter R=0.4 and selected in the rapidity range |y|<2.37 for transverse momenta pT >100 GeV.

Measurements of isolated-photon plus jet cross sections are presented as functions of the photon transverse energy, the jet transverse momentum, the photon-jet invariant mass and the scattering angle in the photon-jet centre-of-mass system.

The leading-logarithm parton-shower predictions from SHERPA and PYTHIA as well as next-to-leading-order QCD calculations from JETPHOX are compared to the measurements.
