The fact that (Formula presented) guarantees that odd powers of (Formula presented) are missing from the moments of (Formula presented) This is required by Hermiticity and time reversal of the corresponding hadronic matrix elements.

At very small t, (Formula presented) becomes large due to the pion pole it contains. However, due to other kinematical factors in front of it, the contribution from the term involving (Formula presented) only becomes important close to (Formula presented) which is never reached at either the HERMES or CLAS experiment.
