摘要：

We present the results of our analysis on charmonia (J/psi and psi') hadroproduction taking into account higher-order QCD effects induced by initial-state radiation in a Monte Carlo framework, with the colour-octet mechanism implemented in the event generation, We find that those colour-octet matrix elements extracted so far from Fermilab Tevatron data for both J/psi and psi' production have to be lowered significantly, We finally make predictions for charmonia production at the LHC, presenting a simple code for a fast simulation with PYTHIA based on the colour-octet model.
