A fit to the invariant mass distribution is performed as a function\nof b-jet multiplicity, to constrain the non-resonant production of new particles described by an effective field theory or in models\ncontaining leptoquarks or $Z^\\prime$ bosons that couple preferentially to third-generation fermions. The constraints on new particles\nimprove on previous results, and the constraints on effective operators include those affecting the anomalous magnetic moment of the\n$\\tau$-lepton.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.155470.v2/t1","@type":"Dataset","description":"The measured unfolded differential cross sections.","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.155470.v2/t2","@type":"Dataset","description":"The combined covariance matrix for the differential cross-section distribution.","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.155470.v2/t3","@type":"Dataset","description":"Statistical covariance matrix for the differential cross-section distribution.","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.155470.v2/t4","@type":"Dataset","description":"Systematic covariance matrix for the differential cross-section distribution.","name":"Table 4"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins2905252?version=2"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/155470"}],"inLanguage":"en","name":"A measurement of the high-mass $\u03c4\\bar\u03c4$ production cross-section at $\\sqrt{s}=13$ TeV with the ATLAS detector and constraints on new particles and couplings","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins2905252?version=2","version":2}
