Description

An integral representation is suggested for generalized parton distributions which automatically satisfies the polynomiality and positivity constraints. This representation has the form of an integral of perturbative triangle diagrams over the masses of three propagators with an appropriate weight depending on these masses. An arbitrary D term can be added
