Determining the inner structure of protons and nuclei in terms of their fundamental constituents has been one of the main tasks of high energy nuclear and particle physics experiments. This quest started as a mapping of the (average) parton densities as a function of longitudinal momentum fraction and resolution scale. Recently, the field has progressed to more differential imaging, where one important development is the description of the event-by-event quantum fluctuations in the wave function of the colliding hadron. In this Review, recent developments on the extraction of proton and nuclear transverse geometry with event-by-event fluctuations from collider experiments at high energy is presented. The importance of this fundamentally interesting physics in other collider experiments like in studies of the properties of the Quark Gluon Plasma is also illustrated.

  1. Factorization of elastic, single, and double diffractive $pp$ scattering

    hep-ph 2026-07 conditional novelty 6.0

    SCET with Glauber operators factorizes elastic/single/double diffractive pp scattering, proving non-universality of hadronic functions versus ep while rapidity anomalous dimensions remain universal.

  2. Revisiting the role of saturation in diffractive vector meson production

    hep-ph 2026-06 unverdicted novelty 5.0

    EMD-corrected LHC data enables a consistent CGC description of coherent and incoherent diffractive J/ψ production in γ+p and γ+Pb via Bayesian inference from combined HERA and LHC measurements.

  3. Nuclear structure and saturation effects from diffractive vector meson production

    hep-ph 2026-05 unverdicted novelty 4.0

    Predictions for vector meson production in light-nucleus UPCs show t-differential observables sensitive to nuclear structure models and saturation suppression that grows with nuclear mass and collision energy.
