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} > $ 700 \\GeV and rapidity $|y| < 1.7$. 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.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.145874.v1/t1","@type":"Dataset","description":"Primary Lund jet plane density for AK4 jets in a one-dimensional representation with bin indices for MC tuning purposes.
