Description

Double parton distributions (DPDs) are used in the QCD description of double parton scattering. The DPDs evolve with hard scales through relatively new QCD evolution equations and obey nontrivial sum rules: momentum and valence quark number sum rules. Based on a constructed numerical program, we present recent results on the QCD evolution of the DPDs. In particular, we discuss the problem how to specify initial conditions which exactly fulfill the above mentioned sum rules. In the current proposals these rules are obeyed only approximately.
