Non-diagonal DVCS and transition GPDs: a unified framework for spinless hadron case γ * π → γππ

Abstract Hadron-to-two-hadron transition generalized parton distributions (GPDs) extend the concept of hadron-to-resonance transition GPDs and provide a unified description of non-diagonal hard exclusive reactions in the generalized Bjorken limit. We present the formalism for the case of spinless ha...
