Abstract
This analysis presents a search for singly-produced vector-like quarks (VLQs) coupling to light quark generations in events with a W or Z boson produced in association with two or more high transverse momentum jets. The vector boson produced in the VLQ decay is reconstructed in the W → ℓν or Z → ℓℓ modes, where ℓ is an electron or a muon. No evidence of VLQs is observed above the expected background in 4.64 fb−1 of data taken in 2011 by the ATLAS experiment at the LHC at a centre-of-mass energy of 7 TeV. A fit to the distribution of the invariant mass of the system composed of the vector boson and the highest transverse momentum jet is used to set limits on the heavy quark production cross section times branching ratio, and mass bounds are obtained for three flavors of VLQs.
