Description
We compute the pion quark Generalized Parton Distribution and quark Double Distributions in a coupled Bethe Salpeter and Dyson Schwinger approach in terms of quarks flavors or isospin states. We use simple analytic expressions inspired by the numerical resolution of Bethe Salpeter and Dyson Schwinger equations. We explicitly check the support and polynomiality properties, and the behavior under charge conjugation or time invariance of our model. We obtain analytic expressions for the Double Distributions and Generalized Parton Distribution at vanishing pion momentum transfer at a low scale. Our model compare very well to experimental pion form factor or parton distribution function data.
