Description
We present the computation of exclusive and inclusive dijet production in electron-proton and electron- nucleus collisions at small-x within the Color Glass Condensate effective field theory. We compute the cross- sections differentially in mean dijet momentum and momentum imbalance, as well as its corresponding elliptic anisotropy. For exclusive dijet production, we employ a dipole model with impact parameter and orientation dependence from a modified McLerran-Venugopalan model that incorporates the finite-size charge density of the target (Refs. 1 & 2). For inclusive dijet production, we confirm and extend existing results in the correlation limit approximation by computing the differential cross-section and elliptic anisotropies from full multi-gluon correlations using the Gaussian approximation of high energy correlators, and Balitsky-Kovchegov evolution with running coupling (Ref. 3). For both exclusive and inclusive production, we highlight kinematical regions for observing potential signals of saturation and measuring multi-gluon correlations in a future Electron-Ion Collider.
