Study of the underlying event in top quark pair production in pp collisions at 13 TeV
Measurements of normalized differential cross sections as functions of the multiplicity and kinematic variables of charged-particle tracks from the underlying event in top quark and antiquark pair production are presented. The measurements are performed in proton-proton collisions at a center-of...

| description | Measurements of normalized differential cross
sections as functions of the multiplicity and kinematic variables of charged-particle tracks from the underlying event in
top quark and antiquark pair production are presented. The
measurements are performed in proton-proton collisions at
a center-of-mass energy of 13 TeV, and are based on data
collected by the CMS experiment at the LHC in 2016 corresponding to an integrated luminosity of 35.9 fb−1. Events
containing one electron, one muon, and two jets from the
hadronization and fragmentation of b quarks are used. These
measurements characterize, for the first time, properties of
the underlying event in top quark pair production and show
no deviation from the universality hypothesis at energy scales
typically above twice the top quark mass. |
