Chiral-odd GPDs in large-N_c QCD

We study the flavor structure of the nucleon's chiral-odd generalized parton distributions (transversity GPDs) in the large-N_c limit of QCD. It is found that in the distributions H_T and E_T-tilde the flavor-nonsinglet component u - d is leading in the 1/N_c expansion, while in E_T and H_T-tilde it is the flavor-singlet component u + d. This pattern is consistent with the flavor structure extracted from hard exclusive pi^0 and eta electroproduction data, assuming that the processes are dominated by the twist-3 mechanism involving the chiral-odd pseudoscalar meson distribution amplitudes.
