Descripción
The cross section for pair production of top quarks (t t ¯ ) with
high transverse momenta is measured in p p collisions, collected with
the CMS detector at the LHC with √{s }=8 TeV in data corresponding
to an integrated luminosity of 19.7 fb-1 . The measurement is
performed using lepton +jets events, where one top quark decays
semileptonically, while the second top quark decays to a hadronic final
state. The hadronic decay is reconstructed as a single, large-radius
jet, and identified as a top quark candidate using jet substructure
techniques. The integrated cross section and the differential cross
sections as a function of top quark pT and rapidity are
measured at particle level within a fiducial region related to the
detector-level requirements and at parton level. The particle-level
integrated cross section is found to be σt t
¯=0.499 ±0.035 (stat +syst )±0.095 (theo )
±0.013 (lumi ) pb for top quark pT>400 GeV . The
parton-level measurement is σt t ¯=1.44
±0.10 (stat +syst )±0.29 (theo ) ±0.04 (lumi ) pb .
The integrated and differential cross section results are compared to
predictions from several event generators.
