In these proceedings, we calculate double-spin asymmetry (DSA) in exclusive dijet production in ep collisions and we demonstrate for the first time that the cos(Φ) angular correlation between the scattered electron and proton is a simultaneous probe of the gluon orbital angular momentum and its interplay with the gluon helicity. We make a rough estimate of the DSA for the kinematics of the Electron–Ion Collider.
