Correlations in Multi-Parton Interactions — •Tomas Kasemets and Markus Diehl — DESY, Hamburg, Germany

Many interesting effects of multi-parton interactions are present already in double parton scattering. The two hard scatterings are correlated via double parton densities. We examine the double Drell-Yan process and the impact of the correlations on the differential cross section. One interesting result is that the spin of the interacting quarks correlate the decay planes of the two vector bosons.
