Descripción
Differential and double-differential cross sections for the production
of top quark pairs in proton-proton collisions at √{s }=13 TeV are
measured as a function of kinematic variables of the top quarks and the
top quark-antiquark (t t ¯) system. In addition, kinematic
variables and multiplicities of jets associated with the t t ¯
production are measured. This analysis is based on data collected by the
CMS experiment at the LHC in 2016 corresponding to an integrated
luminosity of 35.8 fb-1 . The measurements are performed in
the lepton +jets decay channels with a single muon or electron and jets
in the final state. The differential cross sections are presented at the
particle level, within a phase space close to the experimental
acceptance, and at the parton level in the full phase space. The results
are compared to several standard model predictions that use different
methods and approximations. The kinematic variables of the top quarks
and the t t ¯ system are reasonably described in general, though
none predict all the measured distributions. In particular, the
transverse momentum distribution of the top quarks is more steeply
falling than predicted. The kinematic distributions and multiplicities
of jets are adequately modeled by certain combinations of
next-to-leading-order calculations and parton shower models.
