Given the assumed decay of into third-generation SM fermions, the final state can contain multiple $\\tau$-leptons and $b$-quarks. This search is based on a dataset of $pp$ collisions at $\\sqrt{s}=13$ TeV recorded with the ATLAS detector during Run 2 of the Large Hadron Collider, corresponding to an integrated luminosity of up to 140 fb$^{-1}$.. No significant excess above the SM background prediction is observed, and 95% confidence level limits on the cross-section times branching ratio are derived as a function of the vector-like lepton mass. A lower observed (expected) limit of 910 GeV (970 GeV) is set on the vector-like lepton mass. Additionally, the results are interpreted for a supersymmetric model with an $R$-parity violating coupling to the third-generation quarks and leptons. Lower observed (expected) limits are obtained on the higgsino mass at 880 GeV (940 GeV) and on the wino mass at 1170 GeV (1170 GeV).","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.158820.v1/t1","@type":"Dataset","description":"Observed (solid line with markers) and expected (dashed line) 95% CL upper limits on the VLL pair production cross-section (σVLL)...","name":"Figure 12"},{"@id":"https://doi.org/10.17182/hepdata.158820.v1/t2","@type":"Dataset","description":"Observed (solid line with markers) and expected (dashed line) 95% CL upper limits on the higgsino pair production cross-section (σhiggsino)...","name":"Figure 13"},{"@id":"https://doi.org/10.17182/hepdata.158820.v1/t3","@type":"Dataset","description":"Observed (solid line with markers) and expected (dashed line) 95% CL upper limits on the wino pair production cross-section (σwino)...","name":"Figure 14"},{"@id":"https://doi.org/10.17182/hepdata.158820.v1/t4","@type":"Dataset","description":"VLL "4321" cross-sections at NLO order of accuracy obtained by MadGraph.","name":"Table 1 of Auxiliary Material"},{"@id":"https://doi.org/10.17182/hepdata.158820.v1/t5","@type":"Dataset","description":"SUSY RPV LQD higgsino cross-sections at NLO + NLL order of accuracy obtained by Resummino.","name":"Table 2 of Auxiliary Material"},{"@id":"https://doi.org/10.17182/hepdata.158820.v1/t6","@type":"Dataset","description":"SUSY RPV LQD wino cross-sections at NLO + NLL order of accuracy obtained by Resummino.","name":"Table 3 of Auxiliary Material"},{"@id":"https://doi.org/10.17182/hepdata.158820.v1/t7","@type":"Dataset","description":"Cutflow of the selection requirements for VLL signals with mVLL =600, 900, and 1200 GeV.
