$p\bar{p}\to {\Lambda }_c{\bar{\Lambda }}_c$ within a Handbag Picture -- Cross Section and Spin Observables

Abstract

We study the process $p\bar{p}\to {\Lambda }_c{\bar{\Lambda }}_c$ within the generalized parton picture. Our starting point is the double handbag diagram which factorizes into soft generalized parton distributions and a hard subprocess amplitude for $u\bar{u}\to c\bar{c}$. Our cross-section predictions may become interesting in view of forthcoming experiments at FAIR in Darmstadt.
