In photoproduction double parton scattering, the 1⊗2 parton-splitting mechanism boosts resolved-photon cross sections by up to a factor 1.6, and direct photons dominate charm final states for x_γ above 0.3-0.4.
The study of DPS in EIC will allow to reach kinematics of largex, in addition to central kinematics of orderx∼0.001−0.01 that is available at LHC and TEV ATRON

Direct versus resolved photons in DPS in photoproduction on proton and nuclei
In photoproduction double parton scattering, the 1⊗2 parton-splitting mechanism boosts resolved-photon cross sections by up to a factor 1.6, and direct photons dominate charm final states for x_γ above 0.3-0.4.
