Abstract: (APS)
A study of chiral-odd generalized parton distributions (GPDs) of the nucleon is presented in the bag model demonstrating that in this model all four chiral-odd GPDs are nonzero contrary to other claims in literature. The bag model results for the GPDs , , agree with other models within a typical quark model accuracy. We present one of the few quark model calculations where polynomiality is satisfied and the sum rule holds. We confront our results with predictions from the large- limit, and with lattice QCD calculations. We conclude that the bag model successfully catches the main features of chiral-odd GPDs.Note:
