### Description

Double parton scattering (DPS) provides access to information about nucleon structure not accessible in single parton scattering: spatial, spin, and colour correlations between the partons inside the nucleon. For short distances between the two probed partons the double parton distributions (DPDs) containing this information can be calculated in perturbation theory. In this talk I will discuss how a consistent treatment of quark mass effects can be achieved in the evaluation of these short distance $1 \to 2$ splitting DPDs. In addition I will also illustrate how - even without a full calculation from Feynman diagrams - the massive splitting can be approximated at next-to-leading order in the strong coupling.
