Description
The contribution of gluon-photon fusion to dijet production in deeply inelastic scattering is typically analyzed in the small-x regime, whereas quark-photon scattering dominates at large x. The transition between these regimes has received less attention. In this work, we calculate the leading-order, twist-four gluon-photon fusion contribution within a generalized high-twist framework for the intermediate-x region (0.001 < x < 0.1). Comparison with quark-photon scattering, our calculation shows the gluon-photon channel grows as x decreases, becoming indispensible for x < 0.1. These results bridge dijet dynamics across x, connecting large-x LPM effects with small-x saturation phenomena, thereby informing the development of event generators for deeply inelastic scattering at electron-ion colliders.
