The sensitivity is improved by $b$-tagging at least one lower-$p_\\text{T}$ jet in addition to the two highest-$p_\\text{T}$ jets. The data used in this search correspond to an integrated luminosity of 103 $\\text{fb}^{-1}$ collected with a dedicated trijet trigger during the 2017 and 2018 $\\sqrt{s} = 13$ TeV proton--proton collision runs with the ATLAS detector at the LHC. The search looks for resonant peaks in the $b$-tagged dijet invariant mass spectrum over a smoothly falling background.  The background is estimated with an innovative data-driven method based on orthonormal functions. The observed $b$-tagged dijet invariant mass spectrum is compatible with the background-only hypothesis. Upper limits at 95% confidence level on a heavy vector-boson production cross section times branching ratio to a pair of $b$-quarks are derived.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.111056.v1/t1","@type":"Dataset","description":"Background estimate from the FD method with N=3 and data in the SR.","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.111056.v1/t2","@type":"Dataset","description":"The observed (solid) and expected (dashed) 95% CL upper limits on the production of $Z' \\to b\\bar{b}$ in association with...","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.111056.v1/t3","@type":"Dataset","description":"Acceptance and Acceptance times efficiency for the LUV Z' model.","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.111056.v1/t4","@type":"Dataset","description":"Fitted event-level b-tagging selection efficiency as a function of the dijet invariant mass.
