We study inclusive and diffractive dijet production in electron-proton and electron-nucleus collisions within the color glass condensate effective field theory. We compute dijet cross sections differentially in both mean dijet transverse momentum P and recoil momentum Δ, as well as the anisotropy in the relative angle between P and Δ. Our results cover a much larger kinematic range than accessible in previous computations performed in the correlation limit approximation, where it is assumed that |P|≫|Δ|. We validate this approximation in its range of applicability and quantify its failure for |P|≲|Δ|. We also predict significant target-dependent deviations from the correlation limit approximation for |P|>|Δ| and |P|≲Qs, which offers a straightforward test of gluon saturation and access to multigluon distributions at a future Electron-Ion Collider.

Heavy quarks in polarised deep-inelastic scattering at the electron-ion collider
Hekhorn, Felix; Magni, Giacomo; Nocera, Emanuele R.; Rabemananjara, Tanjona R.; Rojo, Juan; Schaus, Adrianne; Stegeman, Roy (Springer, 2024)We extend the FONLL general-mass variableflavour-number scheme to the case of longitudinally polarised DIS structure functions, accounting for perturbative corrections up to O α2 s . We quantify the impact of charm quark ... -
The importance of kinematic twists and genuine saturation effects in dijet production at the Electron-Ion Collider
Boussarie, Renaud; Mäntysaari, Heikki; Salazar, Farid; Schenke, Björn (Springer, 2021)We compute the differential yield for quark anti-quark dijet production in high-energy electron-proton and electron-nucleus collisions at small x as a function of the relative momentum P⊥ and momentum imbalance k⊥ of the ... -
Gluon imaging using azimuthal correlations in diffractive scattering at the Electron-Ion Collider
Mäntysaari, Heikki; Roy, Kaushik; Salazar, Farid; Schenke, Björn (American Physical Society, 2021)We study coherent diffractive photon and vector meson production in electron-proton and electron-nucleus collisions within the Color Glass Condensate effective field theory. We show that electron-photon and electron-vector ... -
Nuclear structure functions at a future electron-ion collider
Aschenauer, E. C.; Fazio, S.; Lamont, M. A. C.; Paukkunen, Hannu; Zurita, P. (American Physical Society, 2017)The quantitative knowledge of heavy nuclei’s partonic structure is currently limited to rather large values of momentum fraction x—robust experimental constraints below x ∼ 10−2 at low resolution scale Q2 are particularly ... -
Jet fragmentation transverse momentum measurements from di-hadron correlations in √s = 7 TeV pp and √sNN = 5.02 TeV p–Pb collisions
ALICE Collaboration (Springer, 2019)The transverse structure of jets was studied via jet fragmentation transverse momentum (jT) distributions, obtained using two-particle correlations in proton-proton and proton-lead collisions, measured with the ALICE ...
