dc.description.abstractNew sets of parameters (“tunes”) for the underlying-event (UE) modelling of the pythia8, pythia6 and herwig++ Monte Carlo event generators are constructed using different parton distribution functions. Combined fits to CMS UE proton–proton (pp) data at s√=7TeV and to UE proton–antiproton (pp¯¯¯) data from the CDF experiment at lower s√, are used to study the UE models and constrain their parameters, providing thereby improved predictions for proton–proton collisions at 13TeV. In addition, it is investigated whether the values of the parameters obtained from fits to UE observables are consistent with the values determined from fitting observables sensitive to double-parton scattering processes. Finally, comparisons are presented of the UE tunes to “minimum bias” (MB) events, multijet, and Drell–Yan (qq¯¯¯→Z/γ∗→ lepton-antilepton+jets) observables at 7 and 8TeV, as well as predictions for MB and UE observables at 13TeVen_US
