Pion Double Parton Distribution within Chiral Quark Soliton Model — •Asli Tandogan — Ruhr University Bochum
The importance of double parton scattering is being revised with the appearance and expectations in the near future of experimental results on multiple hard scattering at LHC. DPDs’ contribition increases when momentum fractions x1 and x2 of two partons coming from the same hadron become small. In our study we consider pion double parton distribution within the chiral quark soliton model. The leading diagram of pion DPD in the model is vanishing which sugggests that quark interaction due to goldstone boson exchange is important to describe the correlations in double parton distributions. In this talk, we present our investigation of the subleading terms in large Nc limit.
