Chiral-odd GPDs for octet baryons p, Σ+, and Ξ0 are calculated in the diquark spectator model, producing transversity distributions, lowest moments of HT and ET+tildeHT, and tensor charges compared to lattice and other models for the proton.

abstract
Using a physically motivated parameterization based on the reggeized diquark model we perform a flavor separation of the chiral-odd generalized parton distributions obtained from both $\pi^0$ and $\eta$ exclusive electroproduction. In our approach we exploit a connection between the chiral-even and chiral-odd reduced helicity amplitudes using Parity transformations that are relevant for a class of models that includes two-component models. We compare our results for $\eta$ production to the previously obtained $\pi^0$ results, and we make predictions for the transverse single spin asymmetry components which will be measured within the Jefferson Lab 12 GeV program.

Chiral-odd generalized parton distributions for the low-lying octet baryons
Chiral-odd GPDs for octet baryons p, Σ+, and Ξ0 are calculated in the diquark spectator model, producing transversity distributions, lowest moments of HT and ET+tildeHT, and tensor charges compared to lattice and other models for the proton.
