The data were collected from 2016 to 2018 by the CMS experiment at the LHC in proton-proton collisions at $\\sqrt{s}=13$ TeV, corresponding to an integrated luminosity of $138 \\mathrm{fb}^{-1}$. The search is performed in a single-lepton final state, where the B' quark candidate is reconstructed from an electron or muon, missing transverse momentum, one large-radius jet, and one small-radius jet if the t quark decays leptonically. The originating particles of large-radius jets are identified using a neural-network-based tagger, and the dominant background contributions are modeled from data using a neural autoregressive flow network. This search is the most sensitive to date to the single production of narrow-width B' quarks, excluding singlet B' quarks with $\\Gamma/m_{\\mathrm{B}'}=5\\%$ for masses between 0.8 and 1.23 TeV. Limits are also placed on the production cross section of single B' quarks produced in association with t quarks, and on the coupling factor of the B' quark to electroweak bosons.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.168733.v1/t1","@type":"Dataset","description":"Distributions of the reconstructed B' quark mass $m_\\mathrm{tW}$ for all selected events.
