Measurement of the $ \mathrm{Z} \to \mu^{+}\mu^{-} $ angular coefficients in pp collisions at $ \sqrt{s} = $ 13 TeV as functions of transverse momentum and rapidity

A measurement of the eight angular polarization coefficients, $ A_0 $ to $ A_7 $, in the cross section for the Drell--Yan production of two muons is presented. The analysis is based on proton-proton (pp) collision data recorded with the CMS detector at the LHC at a center-of-mass energy of $ \sqrt{s}= $ 13 TeV, corresponding to an integrated luminosity of 140 fb$ ^{-1} $. The coefficients are determined double differentially in eight intervals of transverse momentum and two intervals of rapidity of the muon pair $ \mu^{+}\mu^{-} $. The results are presented for the $ \mu^{+}\mu^{-} $ invariant mass range 81--101 GeV and are compared with theoretical predictions calculated at next-to-next-to-leading order in perturbative quantum chromodynamics. The measurement provides relevant information about the underlying partonic dynamics and the Z boson production mechanisms.

#CMSpaper soon on arXiv: Simultaneous measurements of N-subjettiness observables in jets from gluons and light-flavour quarks, and in decays of boosted W bosons and top quarks (CERN-EP-2025-294) https://cds.cern.ch/record/2960043 #StandardModel
Simultaneous measurements of $ N $-subjettiness observables in jets from gluons and light-flavour quarks, and in decays of boosted W bosons and top quarks

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 TeV. The measurement is carried out on dijet events and $ \mathrm{t} \overline{\mathrm{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.
