A measurement of the four-lepton invariant mass spectrum is made with the ATLAS detector, using an integrated luminosity of 36.1 fb$^{-1}$ of proton-proton collisions at $\\sqrt{s}$=13 TeV delivered by the Large Hadron Collider. The differential cross section is measured for events containing two same-flavour opposite-sign lepton pairs, and is corrected for detector effects. It exhibits a rich structure, with different mass regions dominated in the Standard Model by single Z production, Higgs production, and Z boson pair production, and non-negligible interference effects at high invariant masses. In addition, there may be contributions from beyond-the-Standard Model (BSM) physics. The measurement is compared to state-of-the-art Standard Model calculations, which are found to be consistent with the data. These calculations are used to interpret the data in terms of $gg\\to ZZ \\to 4\\ell$ and $Z \\rightarrow 4\\ell$ subprocesses, and to place constraints on a possible BSM contribution.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.84818.v1/t1","@type":"Dataset","description":"Measured and expected differential cross-section $\\text{d}\\sigma / \\text{d} m_{4l}$ as a function of $m_{4l}$","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.84818.v1/t2","@type":"Dataset","description":"Measured and expected differential cross-section $\\text{d}\\sigma / \\text{d} m_{4l}$ as a function of $m_{4l}$ in bin of 0$< p_{T}^{4l} <$20...","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.84818.v1/t3","@type":"Dataset","description":"Measured and expected differential cross-section $\\text{d}\\sigma / \\text{d} m_{4l}$ as a function of $m_{4l}$ in bin of 20$< p_{T}^{4l} <$50...","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.84818.v1/t4","@type":"Dataset","description":"Measured and expected differential cross-section $\\text{d}\\sigma / \\text{d} m_{4l}$ as a function of $m_{4l}$ in bin of 50$< p_{T}^{4l} <$100...","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.84818.v1/t5","@type":"Dataset","description":"Measured and expected differential cross-section $\\text{d}\\sigma / \\text{d} m_{4l}$ as a function of $m_{4l}$ in bin of 100$< p_{T}^{4l} <$600...","name":"Table 5"},{"@id":"https://doi.org/10.17182/hepdata.84818.v1/t6","@type":"Dataset","description":"Measured and expected double differential cross-section $\\text{d}\\sigma / \\text{d} m_{4l}$ as a function of $m_{4l}$ in bin of 0.0$< y_{4l}...","name":"Table 6"},{"@id":"https://doi.org/10.17182/hepdata.84818.v1/t7","@type":"Dataset","description":"Measured and expected double differential cross-section $\\text{d}\\sigma / \\text{d} m_{4l}$ as a function of $m_{4l}$ in bin of 0.4$< y_{4l}...","name":"Table 7"},{"@id":"https://doi.org/10.17182/hepdata.84818.v1/t8","@type":"Dataset","description":"Measured and expected double differential cross-section $\\text{d}\\sigma / \\text{d} m_{4l}$ as a function of $m_{4l}$ in bin of 0.8$< y_{4l}...","name":"Table 8"},{"@id":"https://doi.org/10.17182/hepdata.84818.v1/t9","@type":"Dataset","description":"Measured and expected double differential cross-section $\\text{d}\\sigma / \\text{d} m_{4l}$ as a function of $m_{4l}$ in bin of 1.2$< y_{4l}...","name":"Table 9"},{"@id":"https://doi.org/10.17182/hepdata.84818.v1/t10","@type":"Dataset","description":"Measured and expected double differential cross-section $\\text{d}\\sigma / \\text{d} m_{4l}$ as a function of $m_{4l}$ for MELA$<$1.4 bin","name":"Table 10"},{"@id":"https://doi.org/10.17182/hepdata.84818.v1/t11","@type":"Dataset","description":"Measured and expected double differential cross-section $\\text{d}\\sigma / \\text{d} m_{4l}$ as a function of $m_{4l}$ for MELA$>$1.4 bin","name":"Table 11"},{"@id":"https://doi.org/10.17182/hepdata.84818.v1/t12","@type":"Dataset","description":"Measured and expected double differential cross-section $\\text{d}\\sigma / \\text{d} m_{4l}$ as a function of $m_{4l}$ for $\\mu\\mu\\mu\\mu$ events","name":"Table 12"},{"@id":"https://doi.org/10.17182/hepdata.84818.v1/t13","@type":"Dataset","description":"Measured and expected double differential cross-section $\\text{d}\\sigma / \\text{d} m_{4l}$ as a function of $m_{4l}$ for $eeee$ events","name":"Table 13"},{"@id":"https://doi.org/10.17182/hepdata.84818.v1/t14","@type":"Dataset","description":"Measured and expected double differential cross-section $\\text{d}\\sigma / \\text{d} m_{4l}$ as a function of $m_{4l}$ for $ee\\mu\\mu$ events","name":"Table 14"},{"@id":"https://doi.org/10.17182/hepdata.84818.v1/t15","@type":"Dataset","description":"Systematic covariance matrix for the differential $m_{4l}$ distribution.","name":"Table 15"},{"@id":"https://doi.org/10.17182/hepdata.84818.v1/t16","@type":"Dataset","description":"Statistical covariance matrix for the differential $m_{4l}$ distribution.","name":"Table 16"},{"@id":"https://doi.org/10.17182/hepdata.84818.v1/t17","@type":"Dataset","description":"Background covariance matrix for the differential $m_{4l}$ distribution.","name":"Table 17"},{"@id":"https://doi.org/10.17182/hepdata.84818.v1/t18","@type":"Dataset","description":"Systematic covariance matrix for the differential $m_{4l}$-$p_{T}^{4l}$ distribution.
