Photon-jet correlations and constraints on fragmentation functions
We study the production of a large-${p}_{T}$ photon in association with a jet in proton-proton collisions. We examine the sensitivity of the jet rapidity distribution to the gluon distribution function in the proton. We then assess the sensitivity of various $\mathrm{\text{photon}}+\mathrm{\text{jet}}$ correlation observables to the photon fragmentation functions. We argue …
