We consider the leptoquark (LQ) to be a scalar particle of charge -1/3$e$ coupling to a top quark plus a tau lepton ($\\mathrm{t}\\tau$) or a bottom quark plus a neutrino ($\\mathrm{b}\\nu$), or a vector particle of charge +2/3$e$, coupling to $\\mathrm{t}\\nu$ or $\\mathrm{b}\\tau$. These choices are motivated by models that can explain a series of anomalies observed in the measurement of B meson decays. In this analysis the signatures $\\mathrm{t}\\tau\\nu\\mathrm{b}$ and $\\mathrm{t}\\tau\\nu$ are probed, using data recorded by the CMS experiment at the CERN LHC at $\\sqrt{s} =$ 13 TeV and that correspond to an integrated luminosity of 137 fb$^{-1}$. These signatures have not been previously explored in a dedicated search. The data are found to be in agreement with the standard model prediction. Lower limits at 95% confidence level are set on the LQ mass in the range 0.98-1.73 TeV, depending on the LQ spin and its coupling $\\lambda$ to a lepton and a quark, and assuming equal branching fractions for the two LQ decay modes considered. These are the most stringent constraints to date on the existence of leptoquarks in this scenario.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.104980.v1/t1","@type":"Dataset","description":"Pair leptoquark (LQ) total selection efficiency, accounting for both the decay branching fraction and the event selection, for events that...","name":"Acceptance times efficiency for leptoquark pairs"},{"@id":"https://doi.org/10.17182/hepdata.104980.v1/t2","@type":"Dataset","description":"Single scalar leptoquark (LQs) total selection efficiency, accounting for both the decay branching fraction and the event selection, for events...","name":"Acceptance times efficiency for single scalar leptoquarks"},{"@id":"https://doi.org/10.17182/hepdata.104980.v1/t3","@type":"Dataset","description":"Single vector leptoquark (LQv) k = 0 total selection efficiency, accounting for both the decay branching fraction and the event...","name":"Acceptance times efficiency for single vector leptoquarks, k = 0"},{"@id":"https://doi.org/10.17182/hepdata.104980.v1/t4","@type":"Dataset","description":"Single vector leptoquark (LQv) k = 1 total selection efficiency, accounting for both the decay branching fraction and the event...","name":"Acceptance times efficiency for single vector leptoquarks, k = 1"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1835316?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/104980"}],"inLanguage":"en","name":"Search for singly and pair-produced leptoquarks coupling to third-generation fermions 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/ins1835316?version=1","version":1}
