The data correspond to the full integrated luminosity of 140 fb$^{-1}$ recorded with the ATLAS detector during Run~2 of the Large Hadron Collider. The analysis targets $Q \\to Wb$ decays where the $W$ boson decays leptonically. The data are found to be consistent with the expected Standard Model background, so upper limits are set on the cross-section times branching ratio, and on the coupling of the $Q$ to the Standard Model sector for these two benchmark models. Effects of interference with the Standard Model background are taken into account. For the singlet $T$, the 95% confidence level limit on the coupling strength $\u03ba$ ranges between 0.22 and 0.52 for masses from 1150 to 2300 GeV. For the $(T,B,Y)$ triplet, the limits on $\u03ba$ vary from 0.14 to 0.46 for masses from 1150 to 2600 GeV.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.161563.v2/t1","@type":"Dataset","description":"Distributions of the VLQ-candidate mass, mVLQ, in the (a–c) SRs, (d–f) W+jets CRs and (g–i) tt̄
