Investigating the diffractive gluon jet production in lepton-ion collisions

We study the diffractive jet production in electron-ion collisions in the kinematic region where the mass M-X of the diffractive final state is larger than Q(2). Based on parton saturation framework, predictions are done for the kinematics of future or possible eA machines as the EIC, LHeC, HE-LHeC, and FCC-eA. We analyze the differential cross section as a function of jet (gluon) transverse momentum and from the experimental point of view this observable could be used to extract the saturation scale as a function of x(IP).
