Abstract
A measurement of jet substructure observables is presented using t¯t events in the lepton+jets channel from proton-proton collisions at √s=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, αS(mZ) = 0.115[superscript +0.015][subscript −0.013], is extracted from the substructure data at leading-order plus leading-log accuracy.
