Double c(c)over-bar production at LHCb

Theoretical predictions are presented for the production of two J/psi-mesons, of a J/psi-meson in association with an open charm hadron, and of two open charm hadrons from two c (c) over bar 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.
