Measurement of jet substructure observables in tt¯ events from proton-proton collisions at s=13 TeV

A measurement of jet substructure observables is presented using t\overline{t}events in the \mathrm{lepton}+\text{jets}channel from proton-proton collisions at \sqrt{s}=13\text{ }\text{ }\mathrm{TeV}recorded by the CMS experiment at the LHC, corresponding to an integrated luminosity of 35.9\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1} Multiple jet substructure observables are measured for jets identified as bottom, light-quark, and...
