Summary: | A search for the production of heavy resonances decaying into top quarkantiquark pairs is presented. The analysis is performed in the lepton+jets and fully
hadronic channels using data collected in proton-proton collisions at √
s = 13 TeV using the CMS detector at the LHC, corresponding to an integrated luminosity of 2.6 fb−1
.
The selection is optimized for massive resonances, where the top quarks have large Lorentz
boosts. No evidence for resonant t¯t production is found in the data, and upper limits on the
production cross section of heavy resonances are set. The exclusion limits for resonances
with masses above 2 TeV are significantly improved compared to those of previous analyses
at √
s = 8 TeV. |
