Abstract.

We study the photoproduction of an isolated photon and a jet based on a code of partonic event generator type which includes the full set of next-to-leading order corrections. We compare our results to a recent ZEUS analysis in which an effective \(k_{\mathrm{T}}\) of the incoming partons has been determined. We find that no additional intrinsic \(k_{\mathrm{T}}\) is needed to describe the data.
