Flavor dependence of chiral odd generalized parton distributions and the   tensor charge from the analysis of combined $\pi^0$ and $\eta$ exclusive   electroproduction data
  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.
