This analysis is based on proton-proton collision data recorded at $\\sqrt{s}=13$ TeV with the ATLAS detector at the Large Hadron Collider between 2015 and 2018, corresponding to an integrated luminosity of 139 fb$^{-1}$. After selecting events containing large-radius jets with high track multiplicity, the invariant mass distribution of the two leading jets is scanned to look for an excess above a data-driven estimate of the Standard Model multi-jet background. No significant excess of events is observed and the results are thus used to set $95 \\%$ confidence-level upper limits on the production cross-section times branching ratio of the $Z^\\prime$ to dark quarks as a function of the $Z^\\prime$ mass for various dark-quark scenarios.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.145191.v1/t1","@type":"Dataset","description":"Distribution of the di-jet invariant mass, $m_{\\mathrm{JJ}}$ for the data, the simulated multi-jet background and of some representative signals (models...","name":"Di-jet invariant mass after preselections"},{"@id":"https://doi.org/10.17182/hepdata.145191.v1/t2","@type":"Dataset","description":"Distributions of the number of tracks associated to the leading jet, $n_{track,1}$, for the data, the simulated multi-jet background and...","name":"Leading jet number of tracks after preselections"},{"@id":"https://doi.org/10.17182/hepdata.145191.v1/t3","@type":"Dataset","description":"Distributions of the number of tracks associated to the subleading jet, $n_{track,2}$, for the data, the simulated multi-jet background and...","name":"Sub-leading jet number of tracks after preselections"},{"@id":"https://doi.org/10.17182/hepdata.145191.v1/t4","@type":"Dataset","description":"Distribution of $m_{\\mathrm{JJ}}$ in the SR (black points) compared to the background-only expectation, where the shape is derived from the...","name":"Di-jet invariant mass in SR vs. background-only expectation"},{"@id":"https://doi.org/10.17182/hepdata.145191.v1/t5","@type":"Dataset","description":"Observed and expected limits at 95% CL on the cross-section times branching ratio for the production of dark quarks through...","name":"Observed and expected limits (model A)"},{"@id":"https://doi.org/10.17182/hepdata.145191.v1/t6","@type":"Dataset","description":"The predicted theory cross-section times branching ratio for the production of dark quarks through a $Z^\\prime$ as a function of...","name":"Theory cross-section times branching ratio (model A)"},{"@id":"https://doi.org/10.17182/hepdata.145191.v1/t7","@type":"Dataset","description":"Observed and expected limits at 95% CL on the cross-section times branching ratio for the production of dark quarks through...","name":"Observed and expected limits (model B)"},{"@id":"https://doi.org/10.17182/hepdata.145191.v1/t8","@type":"Dataset","description":"The predicted theory cross-section times branching ratio for the production of dark quarks through a $Z^\\prime$ as a function of...","name":"Theory cross-section times branching ratio (model B)"},{"@id":"https://doi.org/10.17182/hepdata.145191.v1/t9","@type":"Dataset","description":"Observed and expected limits at 95% CL on the cross-section times branching ratio for the production of dark quarks through...","name":"Observed and expected limits (model C)"},{"@id":"https://doi.org/10.17182/hepdata.145191.v1/t10","@type":"Dataset","description":"The predicted theory cross-section times branching ratio for the production of dark quarks through a $Z^\\prime$ as a function of...","name":"Theory cross-section times branching ratio (model C)"},{"@id":"https://doi.org/10.17182/hepdata.145191.v1/t11","@type":"Dataset","description":"Observed and expected limits at 95% CL on the cross-section times branching ratio for the production of dark quarks through...","name":"Observed and expected limits (model D)"},{"@id":"https://doi.org/10.17182/hepdata.145191.v1/t12","@type":"Dataset","description":"The predicted theory cross-section times branching ratio for the production of dark quarks through a $Z^\\prime$ as a function of...","name":"Theory cross-section times branching ratio (model D)"},{"@id":"https://doi.org/10.17182/hepdata.145191.v1/t13","@type":"Dataset","description":"Relative efficiency (in %) of each stage of the analysis selection with respect to the previous one for models A...","name":"Cutflow table for signal points"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins2719976?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/145191"}],"inLanguage":"en","name":"Search for Resonant Production of Dark Quarks in the Dijet Final State with the ATLAS Detector","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins2719976?version=1","version":1}
