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 s $$ sqrt{s} $$ = 13 TeV.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 Deck Bumper 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 Maestro AR/DSR1 T-Harness of the substructure variables, corrected for detector effects, 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.
