Results from a search is presented for pair production of a new heavy quark ($Q$) that decays into a $W$ boson and a light quark ($q$) in the final state where one $W$ boson decays leptonically (to an electron or muon plus a neutrino) and the other $W$ boson decays hadronically. The analysis is performed using an integrated luminosity of 20.3 fb$^{-1}$ of $pp$ collisions at $\\sqrt{s} = 8$ TeV collected by the ATLAS detector at the LHC. No evidence of $Q\\bar{Q}$ production is observed. New chiral quarks with masses below 690 GeV are excluded at 95% confidence level, assuming BR$(Q\\to Wq)=1$. Results are also interpreted in the context of vectorlike quark models, resulting in the limits on the mass of a vectorlike quark in the two-dimensional plane of BR$(Q\\to Wq)$ versus BR$(Q\\to Hq)$\n\nThe main selection requirements for this analysis were:\n- exactly one isolated lepton with pT(lep) > 25 GeV\n- missing transverse momentum ETmiss > 30 GeV\n- \"transverse\" W mass + ETmiss > 60 GeV\n- at least four jets with pT(jet) > 25 GeV\n- zero b-jets\n- a leptonic W candidate consisting of the lepton+ETmiss system with pT > 125 GeV\n- a hadronic W candidate consisting of a dijet system with pT > 200 GeV, 65 GeV < mass 100 GeV, and deltaR < 1.0 between the two jets.\n- two reconstructed heavy quarks (W+1jet systems) with a mass difference less than 120 GeV\n- At least two jets (not used for the hadronic W) with pT > 120 GeV.\n- At least one jet (not used for the hadronic W) with pT > 160 GeV.\n- Scalar sum of |pT| from hadronic W, leptonic W, and two highest pT jets not used for hadronic W  must be > 1.1 TeV\n- Angular cuts between reconstructed objects (see details in paper).","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.71069.v1/t1","@type":"Dataset","description":"The expected and observed 95% CL upper limits on the cross section as a function of $m_Q$ when setting BR$(Q\\to...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.71069.v1/t2","@type":"Dataset","description":"The upper and lower bounds on the range of heavy quark masses expected and observed to be excluded at 95%...","name":"Table 2"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1393281?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/71069"}],"inLanguage":"en","name":"Search for pair production of a new heavy quark that decays into a $W$ boson and a light quark in $pp$ collisions at $\\sqrt{s} = 8$ TeV with the ATLAS detector","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1393281?version=1","version":1}
