Abstract
A measurement of jet substructure observables is presented using data collected
in 2016 by the ATLAS experiment at the LHC with proton-proton collisions at
ps = 13TeV. Large-radius jets groomed with the trimming and soft-drop algorithms are studied.
Dedicated event selections are used to study jets produced by light quarks or gluons, and
hadronically decaying top quarks and W bosons. The observables measured are sensitive
to substructure, and therefore are typically used for tagging large-radius jets from boosted
massive particles. These include the energy correlation functions and the N-subjettiness
variables. The number of subjets and the Les Houches angularity are also considered. The
distributions of the substructure variables, corrected for detector e ects, are compared to
the predictions of various Monte Carlo event generators. They are also compared between
the large-radius jets originating from light quarks or gluons, and hadronically decaying top
quarks and W bosons.
