  "abstract": "Diboson production in association with jets is studied in the fully leptonic final states, pp $\\to$ (Z$\\gamma^*$)(Z/$\\gamma^*$)+jets $\\to$ 2$\\ell$2$\\ell'$+jets, ($\\ell,\\ell'$ = 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 $p_\\mathrm{T}$, pseudorapidity $\\eta$, invariant mass and $\\Delta\\eta$ of the highest-$p_\\mathrm{T}$ and second-highest-$p_\\mathrm{T}$ 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.",
