Abstract
Zt and yr production with Z --> l(+)l_ t --> Wb --> lvb provides the best d etermination of top flavour-changing neutral couplings at the LHC. The boun ds on tc couplings eventually derived from these processes are similar to t hose expected from top decays, while the limits on tu couplings are better by a factor of two. The other significant Z and W decay modes are also inve stigated. (C) 2000 Elsevier Science B.V. All rights reserved.
