Abstract
A search is presented for the pair production of heavy vectorlike quarks (VLQs) that each decay into a 𝑊 boson and a light quark. This study focuses on events where one 𝑊 boson decays into leptons and the other into hadrons. The search analyzed 140 fb−1 of 𝑝𝑝 collision data with √𝑠 =13 TeV, recorded by the ATLAS detector from 2015 to 2018 during run 2 of the Large Hadron Collider. The final state is characterized by a high-transverse-momentum isolated electron or muon, large missing transverse momentum, multiple small-radius jets, and a single large-radius jet identified as originating from the hadronic decay of a boosted 𝑊 boson. With higher center-of-mass energy and integrated luminosity than in the run 1 search, and improved analysis tools, this analysis excludes VLQs (𝑄) with masses below 1530 GeV at 95% confidence level for the branching ratio ℬ(𝑄 →𝑊𝑞) =1, an improvement of 840 GeV on the previous ATLAS limit.
