A Nakanishi-based model illustrating the covariant extension of the pion GPD overlap representation and its ambiguities
A systematic approach for the model building of Generalized Parton Distributions (GPDs), based on their overlap representation within the DGLAP kinematic region and a further covariant extension to the ERBL one, is applied to the valence-quark pion's case, using light-front wave functions inspi...
