Simultaneous measurements of N-subjettiness observables in jets from gluons and light-flavour quarks, and in decays of boosted W bosons and top quarks | CU Experts

; A; bstract; ; ; A simultaneous measurement of 25 substructure observables is presented using large-radius jets with high transverse momentum from proton-proton collisions at; ; ; $$ sqrt{s}=13 $$; ; ; s; ; =; 13; ; ; ; TeV. The measurement is carried out on dijet events and; ; ; $$ toverline{t} $$; ; 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.;
