摘要：

We review the modelling of multiple interactions in the event generator HERWIG++ and study implications of recent tuning efforts to Tevatron and LHC data. It is often said that measurements of the effective cross section for double-parton scattering, sigma(eff), are in contradiction with models of the final state of multi-parton interactions, but we show that the HERWIG++ model is consistent with both and gives stable predictions for underlying event observables at 14 TeV.
