Nucleon-deuteron collision as a probe of the partonic distributionsProceedings of the 40th International Symposium on Multiparticle Dynamics

The one-body partonic distributions in the hadrons are well investigated using electromagnetic or weak interactions. The events with multiple electromagnetic or weak interactions on the same hadron are the very rare. Thus the double parton distributions can be investigated in the events with double QCD hard scattering of partons of the same hadron: it depends not only on the rapidities (or fractional momenta) of the partons but also on a transverse variable. The nucleon-deuteron collision can be a good candidate for this kind of investigations because of the known structure of the deuteron wave function which provides a probe, absent in hadron-hadron collision.
