title: "Figure 12 (lower left)." of "Measurement of differential ZZ + jets production cross sections in pp collisions at $\sqrt{s}$ = 13 TeV"

description: Differential cross sections normalized to the fiducial cross section as a function of the invariant mass of the four-lepton system in events with 2 jets, in the full $m_{4l}$ range
description: Diboson production in association with jets is studied in the fully leptonic final states, $\textrm{pp} \to (\textrm{Z}/\gamma^*)(\textrm{Z}/\gamma^*)+\textrm{jets} \to 2\ell2\ell'+\textrm{jets}$, ($\ell,\ell' = \textrm{e}$ or $\mu$) in proton-proton collisions at a center-of-mass energy of 13 TeV. The data sample corresponds to an integrated luminosity of 138 fb$^{-1}$ collected with the CMS detector at the LHC. Differential distributions and normalized differential cross sections are measured as a function of jet multiplicity, transverse momentum $p_\textrm{T}$, pseudorapidity $\eta$, invariant mass and $\Delta\eta$ of the highest-$p_\textrm{T}$ and second-highest-$p_\textrm{T}$ jets, and as a function of invariant mass of the four-lepton system for events with various jet multiplicities. These differential cross sections are compared with theoretical predictions that mostly agree with the experimental data. However, in a few regions we observe discrepancies between the predicted and measured values. Further improvement of the predictions is required to describe the ZZ+jets production in the whole phase space.

title: "AK4 primary Lund plane density mapped to 1D" of "Measurement of the primary Lund jet plane density in proton-proton collisions at $\sqrt{s}$ = 13 TeV"

description: Primary Lund jet plane density for AK4 jets in a one-dimensional representation with bin indices for MC tuning purposes. The mapping between the bin indices and the physical binning can be imported from the XML file attached to this HepData record using the TUnfoldBinningXML class of ROOT (qualitatively, it corresponds to slicing the Lund plane horizontally from low kT to high kT). All systematic uncertainties are bin-to-bin fully correlated (allowing for sign-changes bin-to-bin), with the exception of the statistical uncertainties from data and MC, for which a separate correlation matrix is provided in this HepData record.
description: A measurement of the primary Lund jet plane (LJP) density in inclusive jet production in proton-proton collisions is presented. The analysis uses $138\fbinv$ of data collected by the CMS experiment at $\sqrt{s} = 13$ TeV. The LJP, a representation of the phase space of emissions inside jets, is constructed using iterative jet declustering. The transverse momentum $k_\text{T}$ and the splitting angle $\Delta R$ of an emission relative to its emitter are measured at each step of the jet declustering process. The average density of emissions in $\ln(k_\mathrm{T}/\text{GeV})$ and $\ln (R/\Delta R)$ is measured for jets with distance parameters $R = 0.4$ or $0.8$ and transverse momentum $p_\mathrm{T} &gt; $ 700 \GeV and rapidity $|y| &lt; 1.7$. The jet substructure is measured using the charged-particle tracks of the jet. The measured distributions, unfolded to the level of stable particles, are compared with theoretical predictions from state-of-the-art simulations and with perturbative quantum chromodynamics calculations. Due to the ability of the LJP to factorize physical effects, the measurement can be used to improve different aspects of the physics modeling in event generators.

title: "pp abs norm" of "Measurements of the suppression and correlations of dijets in Pb+Pb collisions at $\sqrt{s_{_\text{NN}}}$ = 5.02 TeV"

description: absolutely normalized dijet cross sections from pp collisions
description: Studies of the correlations of the two highest transverse momentum (leading)jets in individual Pb+Pb collision events can provide information about themechanism of jet quenching by the hot and dense matter created in suchcollisions. In Pb+Pb and $pp$ collisions at $\sqrt{s_{_\text{NN}}}$ = 5.02TeV, measurements of the leading dijet transverse momentum ($p_{\mathrm{T}}$)correlations are presented. Additionally, measurements in Pb+Pb collisions ofthe dijet pair nuclear modification factors projected along leading andsubleading jet $p_{\mathrm{T}}$ are made. The measurements are performed usingthe ATLAS detector at the LHC with 260 ${\mathrm {pb}^{-1}}$ of $pp$ datacollected in 2017 and 2.2 ${\mathrm {nb}^{-1}}$ of Pb+Pb data collected in2015 and 2018. An unfolding procedure is applied to the two-dimensionalleading and subleading jet $p_{\mathrm{T}}$ distributions to account forexperimental effects in the measurement of both jets. Results are provided fordijets with leading jet $p_{\mathrm{T}}$ greater than 100 GeV. Measurements ofthe dijet-yield-normalized $x_{\mathrm{J}}$ distributions in Pb+Pb collisionsshow an increased fraction of imbalanced jets compared to $pp$ collisions;these measurements are in agreement with previous measurements of the samequantity at 2.76 TeV in the overlapping kinematic range. Measurements of theabsolutely-normalized dijet rate in Pb+Pb and $pp$ collisions are alsopresented, and show that balanced dijets are significantly more suppressedthan imbalanced dijets in Pb+Pb collisions. It is observed in themeasurements of the pair nuclear modification factors that the subleadingjets are significantly suppressed relative to leading jets with$p_{\mathrm{T}}$ between 100 and 316 GeV for all centralities in Pb+Pbcollisions.
