摘      要：Exclusive π^(0) electroproduction is analyzed within the handbag approach based on Generalized Parton Distribution(GPDs)*** consider the leading-twist contribution together with the transversity *** is shown that the transversity GPDs H_(T) and E_(T) are essential in the description of the π^(0) cross *** for the future Electron-Ion Collider of China(EicC)energy range are *** is found that transversity dominanceσ_(T)σ_(L),observed at low energies,is valid up to the EicC energy range.
