The data sample was collected in 2016 and corresponds to an integrated luminosity of 35.9fb\u22121. Final states studied for TTbar production include those where one of the T quarks decays via T \u2192 tZ and the other via T \u2192 bW, tZ, or tH, where H is a Higgs boson. For the BBbar case, final states include those where one of the B quarks decays via B \u2192 bZ and the other B \u2192 tW, bZ, or bH. Events with two oppositely charged electrons or muons, consistent with coming from the decay of a Z boson, and jets are investigated. The number of observed events is consistent with standard model background estimations. Lower limits at 95% confidence level are placed on the masses of the T and B quarks for a range of branching fractions. Assuming 100% branching fractions for T \u2192 tZ, and  B \u2192 bZ, T and B quark mass values below 1280 and 1130 GeV, respectively, are excluded.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.85746.v2/t1","@type":"Dataset","description":"The $S_{\\rm T}$ distribution for group A before fitting.","name":"Figure3a"},{"@id":"https://doi.org/10.17182/hepdata.85746.v2/t2","@type":"Dataset","description":"The $S_{\\rm T}$ distribution for group B before fitting.","name":"Figure3b"},{"@id":"https://doi.org/10.17182/hepdata.85746.v2/t3","@type":"Dataset","description":"The $S_{\\rm T}$ distribution for group C before fitting.","name":"Figure3c"},{"@id":"https://doi.org/10.17182/hepdata.85746.v2/t4","@type":"Dataset","description":"The $S_{\\rm T}$ distribution for group D before fitting.","name":"Figure3d"},{"@id":"https://doi.org/10.17182/hepdata.85746.v2/t5","@type":"Dataset","description":"The observed and expected 95% CL upper limits on the $T\\bar T$ cross section as a function of the T...","name":"Figure4a"},{"@id":"https://doi.org/10.17182/hepdata.85746.v2/t6","@type":"Dataset","description":"The observed and expected 95% CL upper limits on the $T\\bar T$ cross section as a function of the T...","name":"Figure4b"},{"@id":"https://doi.org/10.17182/hepdata.85746.v2/t7","@type":"Dataset","description":"The observed and expected 95% CL upper limits on the $T\\bar T$ cross section as a function of the T...","name":"Figure4c"},{"@id":"https://doi.org/10.17182/hepdata.85746.v2/t8","@type":"Dataset","description":"The number of observed events and the predicted number of SM background events in the $T\\bar T$ search using electron...","name":"Table6"},{"@id":"https://doi.org/10.17182/hepdata.85746.v2/t9","@type":"Dataset","description":"The number of observed events and the predicted number of SM background events in the $T\\bar T$ search using muon...","name":"Table7"},{"@id":"https://doi.org/10.17182/hepdata.85746.v2/t10","@type":"Dataset","description":"The $S_{\\rm T}$ distribution for 1b event category for data and the expected background before fitting.","name":"Figure6a"},{"@id":"https://doi.org/10.17182/hepdata.85746.v2/t11","@type":"Dataset","description":"The $S_{\\rm T}$ distribution for 2b event category for data and the expected background.","name":"Figure6b"},{"@id":"https://doi.org/10.17182/hepdata.85746.v2/t12","@type":"Dataset","description":"The $S_{\\rm T}$ distribution for boosted t event category for data and the expected background.","name":"Figure6c"},{"@id":"https://doi.org/10.17182/hepdata.85746.v2/t13","@type":"Dataset","description":"The $S_{\\rm T}$ distribution for boosted H event category for data and the expected background.","name":"Figure6d"},{"@id":"https://doi.org/10.17182/hepdata.85746.v2/t14","@type":"Dataset","description":"The $S_{\\rm T}$ distribution for boosted Z event category for data and the expected background.","name":"Figure6e"},{"@id":"https://doi.org/10.17182/hepdata.85746.v2/t15","@type":"Dataset","description":"The observed and expected 95% CL upper limits on the $B\\bar B$ cross section as a function of the B...","name":"Figure7a"},{"@id":"https://doi.org/10.17182/hepdata.85746.v2/t16","@type":"Dataset","description":"The observed and expected 95% CL upper limits on the $B\\bar B$ cross section as a function of the B...","name":"Figure7b"},{"@id":"https://doi.org/10.17182/hepdata.85746.v2/t17","@type":"Dataset","description":"The observed and expected 95% CL upper limits on the $B\\bar B$ cross section as a function of the B...","name":"Figure7c"},{"@id":"https://doi.org/10.17182/hepdata.85746.v2/t18","@type":"Dataset","description":"The number of observed events and the predicted number of SM background events in the $B\\bar B$ search using electron...","name":"Table8"},{"@id":"https://doi.org/10.17182/hepdata.85746.v2/t19","@type":"Dataset","description":"The number of observed events and the predicted number of SM background events in the $B\\bar B$ search using muon...","name":"Table9"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1711260?version=2"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/85746"}],"inLanguage":"en","name":"Search for vector-like quarks in events with two oppositely charged leptons and jets in proton-proton collisions at $\\sqrt{s} =$ 13 TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1711260?version=2","version":2}
