Experimental processes that are sensitive to parton Wigner distributions provide a powerful tool to advance
our understanding of proton structure. In this work, we compute gluon Wigner and Husimi distributions of
protons within the color glass condensate framework, which includes a spatially dependent McLerranVenugopalan initial configuration and the explicit numerical solution of the Jalilian-Marian–Iancu–
McLerran–Weigert–Leonidov–Kovner equations. We determine the leading anisotropy of the Wigner and
Husimi distributions as a function of the angle between the impact parameter and transverse momentum. We
study experimental signatures of these angular correlations at a proposed electron-ion collider by computing
coherent diffractive dijet production cross sections in e þ p collisions within the same framework.
Specifically, we predict the elliptic modulation of the cross section as a function of the relative angle
between the nucleon recoil and dijet transverse momentum for a wide kinematical range.We further predict its
dependence on the collision energy, which is dominated by the growth of the proton with decreasing x.

Intrinsic charm quark valence distribution of the proton
Ball, Richard D.; Candido, Alessandro; Cruz-Martinez, Juan; Forte, Stefano; Giani, Tommaso; Hekhorn, Felix; Magni, Giacomo; Nocera, Emanuele R.; Rojo, Juan; Stegeman, Roy (American Physical Society (APS), 2024)We provide a first quantitative indication that the wave function of the proton contains unequal distributions of charm quarks and antiquarks, i.e. a nonvanishing intrinsic valence charm distribution. A significant ... -
NNLO nuclear parton distribution functions with electroweak-boson production data from the LHC
Helenius, Ilkka; Walt, Marina; Vogelsang, Werner (American Physical Society (APS), 2022)We present new sets of nuclear parton distribution functions (nPDFs) at next-to-leading order and next-to-next-to-leading order in perturbative QCD. Our analyses are based on deeply inelastic scattering data with charged-lepton ... -
Proton hot spots and exclusive vector meson production
Demirci, S.; Lappi, T.; Schlichting, S. (American Physical Society (APS), 2022)We explore consequences of the existence of gluonic hot spots inside the proton for coherent and incoherent exclusive vector meson production cross sections in deep inelastic scattering. By working in the dilute limit of ... -
