摘要：

We investigate the double parton distributions (DPDs) for a positroniumlike bound state using light-front QED. We incorporate the higher Fock three-particle component of the state, which includes a photon. We obtain the overlap representation of the DPDs in terms of the three-particle light-front wave functions. Our calculation explores the correlations between the momentum fractions of the particles probed and the transverse distance between them, without any assumption of factorization between them. We also investigate the behavior of the DPDs near the kinematical boundary when the sum of the momentum fractions is close to 1.
