Abstract
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 HTq(x,ξ,t), ETq(x,ξ,t), H˜Tq(x,ξ,t) 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 ∫dxE˜Tq(x,ξ,t)=0 holds. We confront our results with predictions from the large-Nc limit, and with lattice QCD calculations. We conclude that the bag model successfully catches the main features of chiral-odd GPDs.
