Description

Photoproduction and diffraction are complementary to the DIS regime usually considered at $ep$ colliders. They contribute significantly to the hadronic final-state at experiments like HERA and the upcoming EIC and are hence of vital interest for, e.g., jet studies in these setups.

In this talk I will present recent calculations of jet production in the photoproduction and diffractive channels. For the first time, NLO QCD accuracy matched to parton showers is reached for these regions. In the photoproduction regime, we quantify the sensitivity of EIC jet measurements to the currently poorly constrained parton-in-photon PDFs, demonstrating the collider's potential to resolve the photon's hadronic structure. For diffraction, we compare against data form ZEUS and H1 and study the impact of future EIC data.
