Talk 06. Strong Interactions and Hadron Physics Strong Interactions and Hadron Physics


Gerrit Van Onsem (CERN)


New sets of CMS underlying-event tunes are presented for the PYTHIA 8 with various colour reconnection models, and Herwig 7 event generator. Comparisons of the predictions of the new tunes are provided for observables sensitive to the global underlying event, to soft multiparton interactions, and to double-parton scattering contributions, as well as for observables measured in various final states, such as multijet, Drell-Yan, and top quark-antiquark pair production. The measurements characterizing the properties of the underlying event in top quark pair production and the Drell-Yan processes are also presented.
