Title: Jet Tomography of the Proton and Its Enabling Technologies

Recent theoretical advances have elevated jet studies in electron-proton scattering as a powerful new method for investigating the proton's quantum phase-space density, a core focus of the upcoming Electron-Ion Collider (EIC). As construction of the EIC progresses, reexamining data from its precursor, HERA, becomes invaluable, especially in light of new theoretical frameworks. In this colloquium, I will present our latest measurements of jets and their substructure at HERA, which have pioneered the use of a key AI/ML technique enabling much higher dimensional measurements. I'll also discuss ongoing R&D efforts in high-granularity calorimetry, enabled by advances in silicon-photomultiplier technology, essential for future jet analyses at the EIC.Abstract:
