Doubly charmed baryon production in hadronic experiments

In the leading order of perturbative QCD one calculates the total and differential cross-sections for the hadronic production of doubly charmed baryons $Ⅺcc$ and $Ⅺcc*$ in different experiments. The experimental evaluation of cross-sections for the $J/Ψ+D+D̄$ production would allow one to decrease the uncertainty in the determination of cross-sections for the doubly charmed baryons due to the choice of $αs$ and $mc.$
