Evidence of strong proton shape fluctuations from incoherent diffraction
read the original abstract
We show within the saturation framework that measurements of exclusive vector meson production at high energy provide evidence for strong geometric fluctuations of the proton. In comparison, the effect of saturation scale and color charge fluctuations is weak. This knowledge will allow detailed future measurements of the incoherent cross section to tightly constrain the fluctuating geometry of the proton as a function of the parton momentum fraction $x$.

When JIMWLK evolution really matters: the example of incoherent diffraction
JIMWLK evolution gives larger incoherent diffraction cross sections than the Gaussian approximation for photon-nucleus collisions because the latter is invalid for four-gluon starting correlators.

First measurements of v_n (n=2-4) in 5.36 TeV O+O and Ne+Ne collisions show enhanced v2 in central neon collisions consistent with prolate nuclear deformation.

Nuclear structure and saturation effects from diffractive vector meson production
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.
