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.

Double D-meson production in proton-proton and proton-lead collisions at the LHC
Helenius, Ilkka; Paukkunen, Hannu (Elsevier BV, 2020)We consider the simultaneous production of two heavy-flavoured hadrons – particularly D mesons – at the LHC. We base our calculations on collinearly factorized QCD at next-to-leading order, using the contemporary parton ... -
EPPS16: nuclear parton distributions with LHC data
Eskola, Kari; Paakkinen, Petja; Paukkunen, Hannu; Salgado, Carlos A. (Springer, 2017)We introduce a global analysis of collinearly factorized nuclear parton distribution functions (PDFs) including, for the first time, data constraints from LHC proton–lead collisions. In comparison to our previous analysis, ... -
First global next-to-leading order determination of diffractive parton distribution functions and their uncertainties within the xFitter framework
Goharipour, Muhammad; Khanpour, Hamzeh; Guzey, Vadim (Springer, 2018)We present GKG18-DPDFs, a next-to-leading order (NLO) QCD analysis of diffractive parton distribution functions (diffractive PDFs) and their uncertainties. This is the first global set of diffractive PDFs determined ... -
Applicability of pion–nucleus Drell–Yan data in global analysis of nuclear parton distribution functions
Paakkinen, Petja; Eskola, Kari; Paukkunen, Hannu (Elsevier B.V., 2017)Despite the success of modern nuclear parton distribution functions (nPDFs) in describing nuclear hard-process data, they still suffer from large uncertainties. One of the poorly constrained features is the possible asymmetry ... -
Constraints on nuclear parton distributions from dijet photoproduction at the LHC
Guzey, Vadim; Klasen, Michael (Springer, 2019)Using QCD calculations of the cross section of inclusive dijet photoproduction in Pb–Pb ultraperipheral collisions in the LHC kinematics as pseudo-data, we study the effect of including these data using the Bayesian ...
