Improved mapping of ccbar onto charmonium states
C. Brenner Mariotto, M. B. Gay Ducati, G. Ingelman
We discuss the relative rates of different charmonium states and introduce an improved model for mapping the continuous ccbar mass spectrum on the physical charmonium resonances.

Soft and hard QCD in charmonium production
C. Brenner Mariotto, M. B. Gay Ducati, G. Ingelman
Hard and soft QCD dynamics are both important in charmonium hadroproduction, as presented here through a next-to-leading order QCD matrix element calculation combined with the colo…
