Descripción
The mass of the top quark is measured using a sample of {{
{t}}\overline{{ {t}}}} events collected by the CMS detector using
proton-proton collisions at √{s}=13 {TeV} at the CERN LHC. Events
are selected with one isolated muon or electron and at least four jets
from data corresponding to an integrated luminosity of 35.9 {fb}^{-1}.
For each event the mass is reconstructed from a kinematic fit of the
decay products to a {{ {t}}\overline{{ {t}}}} hypothesis. Using the
ideogram method, the top quark mass is determined simultaneously with an
overall jet energy scale factor (JSF), constrained by the mass of the W
boson in { {q}} \overline{{ {q}}} ^' decays. The measurement is
calibrated on samples simulated at next-to-leading order matched to a
leading-order parton shower. The top quark mass is found to be 172.25
± 0.08 {(stat+JSF)} ± 0.62 {(syst)} {GeV} . The dependence
of this result on the kinematic properties of the event is studied and
compared to predictions of different models of {{ {t}}\overline{{ {t}}}}
production, and no indications of a bias in the measurements are
observed.
