We study the spin-flavor structure of the nucleon's chiral-odd generalized parton distributions (transversity GPDs) in the large-N_c limit of QCD. In contrast to the chiral-even case, only three combinations of the four chiral-odd GPDs are nonzero in the leading order of the 1/N_c expansion: E-bar_T = E_T+2H-tilde_T, H_T, and E-tilde_T. The degeneracy is explained by the absence of spin-orbit interactions correlating the transverse momentum transfer with the transverse quark spin. It can also be deduced from the natural N_c scaling of the quark-nucleon helicity amplitudes associated with the GPDs. In the GPD E-bar_T the flavor-singlet component u+d is leading in the 1/N_c expansion, while in H_T and E-tilde_T it is the flavor-nonsinglet components u–d. Furthermore, the large-N_c relations are consistent with the spin-flavor structure extracted from hard exclusive π⁰ and η electroproduction data, if it is assumed that the processes are mediated by twist-3 amplitudes involving the chiral-odd GPDs and the chiral-odd pseudoscalar meson distribution amplitudes.
