“…The observable is dominated by the gluonic contributions if the dijet is a pair of heavy quark and antiquark [390], or at small-x [391], which can be very robust at EIC with high energy. Meanwhile, it is also suggested that F q 14 can be measured through the same asymmetry in the exclusive double Drell-Yan process πN → (l − 1 l + 1 )(l − 2 l + 2 )N [392], as well as the exclusive double production of pseudoscalar quarkonia (η c or η b ) in nucleon-nucleon scattering [393]. Again, the analyses in [390,393] are only at tree level, while complication of rapidity renormalization has not been considered.…”

“…Related work includes [96], where it was suggested to study forward diffractive quarkonia production in p + p collisions to probe the Weizsäcker-Williams gluon distribution and [97], where access to the gluon Wigner distributions via ultraperipheral p + A collisions was discussed. Exclusive double production of pseudoscalar quarkonia and its relation to the gluon Wigner distributions in nucleon-nucleon collisions was explored in [98]. Exclusive diffractive two-and three-jet production in photon-hadron scattering within k T factorization and the cancellation of IR, collinear and rapidity singularities for the two-jet cross section was studied in [99].…”

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 McLerran-Venugopalan initial configuration and the explicit numerical solution of the JIMWLK equations. We determine the leading anisotropy of the Wigner and Husimi distributions as a function of the angle between 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+p collisions within the same framework. Specifically, we predict the elliptic modulation of the cross section as a function of the relative angle between nucleon recoil and dijet transverse momentum for a wide kinematical range. We further predict its dependence on collision energy, which is dominated by the growth of the proton with decreasing x. * heikki.mantysaari@jyu.fi † nmueller@bnl.gov ‡ bschenke@bnl.gov arXiv:1902.05087v2 [hep-ph]

“…In [434] it was shown that the production of two pseudoscalar quarkonia (e.g. η c η c , η c η b or η b η b ) in exclusive hadronic collisions, where both hadrons remain intact, is a direct probe of GTMDs for gluons at moderate x (Fig.…”

We review the prospects for quarkonium-production studies in proton and nuclear collisions accessible during the upcoming phases of the CERN Large Hadron Collider operation after 2021, including the ultimate high-luminosity phase, with increased luminosities compared to LHC Runs 1 and 2. We address the current experimental and theoretical open issues in the field and the perspectives for future studies in quarkoniumrelated physics through the exploitation of the huge data samples to be collected in proton-proton, with integrated luminosities reaching up to L = 3 ab −1 , in proton-nucleus and in nucleus-nucleus collisions, both in the collider and fixed-target modes. Such investigations include, among others, those of: (i) the quarkonia produced in association with other hard particles; (ii) the χ Q and η Q down to small transverse momenta; (iii) the constraints brought in by quarkonia on gluon PDFs, nuclear PDFs, TMDs, GPDs and GTMDs, as well as on the low-x parton dynamics; (iv) the gluon Sivers effect in polarised-nucleon collisions; (v) the properties of the quark-gluon plasma produced in ultra-relativistic heavy-ion collisions and of collective partonic effects in general; and (vi) double and triple parton scatterings.
