The Deep Underground Neutrino Experiment (DUNE) is a next-generation neutrino oscillation experiment based in the US, which is scheduled to begin operations in the coming decade. DUNE employs ten-kiloton-scale Liquid Argon Time Projection Chamber (LArTPC) technology to detect neutrinos via their interactions with argon nuclei. ProtoDUNE, as prototypes for DUNE, was developed to demonstrate the scalability and performance of the technology. Beyond its role in detector R&D, ProtoDUNE also serves a physics purpose, which is to measure hadron-argon interactions in the energy regime relevant to DUNE. Such measurements are essential because a considerable amount of hadrons are involved in neutrino-argon interactions, complicating neutrino reconstruction particularly through an effect known as final-state interactions (FSI), where neutrino-produced hadrons undergo further scattering before exiting the nucleus. In this talk, I will present the status and prospects of hadron-argon cross-section measurements at ProtoDUNE, with a focus on the 1 GeV/c beam pion and proton analyses, and discuss how these results will contribute to DUNE's physics program.
