| dc.description | We study proton-antiproton annihilation into $Λ_c \barΛ_c$ pairs within the generalized parton picture. Our starting point is the double handbag diagram which is shown to factorize into soft generalized parton distributions for the $p \to Λ_c$ (and $\bar{p} \to \barΛ_c$) transition and a hard subprocess amplitude for $u \bar{u} \to c \bar{c}$. Thereby the mass of the charm quark is taken as the hard scale so that our results are not restricted to large scattering angles and/or incredibly large energies. Modelling the generalized parton distributions for the $p\to Λ_c$ transition by an overlap of simple quark-diquark light-cone wave functions we make first predictions for $p\to Λ_c$ transition form factors and unpolarized $p\bar{p} \to Λ_c \barΛ_c$ cross sections. Our findings may become interesting in view of forthcoming experiments at FAIR in Darmstadt. | |
