Measurement of jet substructure observables in t t events from proton-proton collisions at s =13 TeV measurement of jet substructure observables
A measurement of jet substructure observables is presented using t¯t events in the lepton þ jets channel from proton-proton collisions at ffiffi s p ¼ 13 TeV recorded by the CMS experiment at the LHC, corresponding to an integrated luminosity of 35.9 fb−1.

| description | A measurement of jet substructure observables is presented using t¯t events in the lepton þ jets channel
from proton-proton collisions at ffiffi
s p ¼ 13 TeV recorded by the CMS experiment at the LHC,
corresponding to an integrated luminosity of 35.9 fb−1. Multiple jet substructure observables are measured
for jets identified as bottom, light-quark, and gluon jets, as well as for inclusive jets (no flavor information).
The results are unfolded to the particle level and compared to next-to-leading-order predictions from
POWHEG interfaced with the parton shower generators PYTHIA 8 and HERWIG 7, as well as from SHERPA 2
and DIRE 2. A value of the strong coupling at the Z boson mass, αSðmZÞ ¼ 0.115þ0.015 −0.013 , is extracted from the
substructure data at leading-order plus leading-log accuracy |
