Measurements of triple-differential cross sections for inclusive isolated-photon+jet events in pp collisions at 𝑠�√=8TeV

Abstract

Measurements are presented of the triple-differential cross section for inclusive isolated-photon+jet events in pp collisions at 𝑠√=8 TeV as a function of photon transverse momentum (𝑝γT), photon pseudorapidity (𝜂γ), and jet pseudorapidity (𝜂jet). The data correspond to an integrated luminosity of 19.7fb−1 that probe a broad range of the available phase space, for |𝜂γ|<1.44 and 1.57<|𝜂γ|<2.50, |𝜂jet|<2.5, 40<𝑝γT<1000 GeV, and jet transverse momentum, 𝑝jetT, > 25GeV. The measurements are compared to next-to-leading order perturbative quantum chromodynamics calculations, which reproduce the data within uncertainties.
