Description

Ultra-Peripheral Collisions (UPCs) at the LHC are the highest energy photon-proton and photon-nucleus collisions accessible anywhere, while the future EIC will collide electrons with protons and nuclei, allowing high-precision measurements over a wide range of Q^2. These collisions are important probes of structure functions and generalized parton distributions (GPDs), with the capability to reach small Bjorken-x values where shadowing and saturation may be important. In this talk, I will discuss how UPC and EIC measurements can be used to measure parton distributions, survey recent results, and discuss some of the theoretical and experimental challenges of these measurements.
