Abstract:

A simultaneous measurement of 25 substructure observables is presented using
large-radius jets with high transverse momentum from proton-proton collisions at √s = 13 TeV. The measurement is carried out on dijet events and t¯t events enriched in Lorentz-boosted W bosons and top quarks decaying hadronically. The three data samples consist of jets with one, two, or three prongs from the showering and hadronization of a gluon or light-flavour quark, two quarks, or three quarks, respectively. The data correspond to an integrated luminosity of 138 fb$^{-1}$, recorded by the CMS experiment in 2016–2018. A detailed characterization of the jet substructure is provided using a 6-body basis of N -subjettiness observables that overconstrains the phase space of the resolved emissions in the jet. The measurements are unfolded to the level of stable particles, and an estimate of the particle-level correlations between observables is provided, ensuring that the results can be used to systematically assess and refine the modelling of radiation in jets.
