Description
Quark and gluon helicity flip generalized parton distributions (GPDs)
are seen to be a convenient tool to address the transversity quark and gluon structure of the nucleon.
In order to construct a theoretically consistent parametrization of these hadronic matrix elements,
we work out the set of combinations of those GPDs suitable for the
SO(3)
partial wave (PW) expansion in the cross-channel. This universal result will help to build up a flexible parametrization
of these important hadronic non-perturbative quantities. We also discuss the possible phenomenological applications.
