Theoretical predictions are presented for the production of two J=c -mesons, of a J=c -meson in association with an open charm hadron, and of two open charm hadrons from two c " c pairs in the LHC conditions. Processes in both single-and double-parton scattering mechanisms are taken into consideration. Special attention is paid to the kinematic limits of the LHCb detector, for which comparison with the newest experimental data is carried out.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
