Abstract

We study parton distributions for two partons, a quark and a gluon, in the light-front dressed quark model, with a focus on the correlations between the two partons. The model calculation leads to sizable spin-spin and spin-kinematic correlations of interest for studies of double parton scattering in high-energy collisions. In particular, we find that the transverse dependence of the double parton distributions (DPDs) does not factorize within the model. The results give insight into the strengths of the correlations in different kinematical regions, which can help in constructing input DPDs in cross-section calculations.
