Search for heavy vector-like quarks coupling to light quarks in proton-proton collisions at sqrt{s} =7 TeV with the ATLAS detector
Original language description
This Letter presents a search for singly produced vector-like quarks, Q, coupling to light quarks, q. The search is sensitive to both charged current (CC) and neutral current (NC) processes, ppQqWqq and ppQqZqq with a leptonic decay of the vector gauge boson. In 1.04 fb1 of data taken in 2011 by the ATLAS experiment at a center-of-mass energy s =7 TeV, no evidence of such heavy vector-like quarks is observed above the expected Standard Model background. Limits on the heavy vector-like quark production cross section times branching ratio as a function of mass mQ are obtained.
