Abstract
Explicit expressions for pion correlators are derived in position-space, employing Chiral Perturbation Theory (ChPT). Resonance exchange contributions are included to test the range of applicability of the leading-order ChPT expressions. The obtained results will be useful for a forthcoming Lattice-QCD study of double parton distributions in the pion.
