Our original suggestion to investigate exclusive π o electroproduction as a method for extracting from data the tensor charge, transversity and other quantities related to chiral odd generalized parton distributions is further examined. We now explain the details of the process: (i) the connection between the helicity description and the Cartesian basis; (ii) the dependence on the momentum transfer squared Q 2 and (iii) the angular momentum, parity and charge conjugation constraints (J PC quantum numbers). © 2012 IOP Publishing Ltd.

Abstract
Our original suggestion to investigate exclusive π o electroproduction as a method for extracting from data the tensor charge, transversity and other quantities related to chiral odd generalized parton distributions is further examined. We now explain the details of the process: (i) the connection between the helicity description and the Cartesian basis; (ii) the dependence on the momentum transfer squared Q 2 and (iii) the angular momentum, parity and charge conjugation constraints (J PC quantum numbers). © 2012 IOP Publishing Ltd.
