Description
Recent studies of associated-quarkonium production at the LHC and the Tevatron have pointed at values of $\sigma_{\rm eff}$ significantly smaller than those extracted from jet-related observables, on the order of 5-10 mb. Other studies carried out by LHCb in the forward rapidity region pointed at more usual values close to 15-20 mb. I will report on these and propose possible explanations for such disparate values.
