A light-cone meson-baryon model is used to compute the eight nonzero twist-3 generalized parton distributions of ubar and dbar sea quarks at zero skewness, plus the derived e(x) and orbital angular momentum.
1, we plot the chiral-even GPDs associated with Γ = 1, namely, H ¯u/P 2 , H ¯d/P 2 , E ¯u/P 2 , and E ¯d/P 2 at ξ = 0
