Multilepton production via top flavour-changing neutral couplings at the CERN LHC
F. del Aguila, J. A. Aguilar-Saavedra
Abstract
Zt and gamma t production with Z -> l+ l- and t -> Wb -> l nu b provides the best determination of top flavour-changing neutral couplings at the LHC. The bounds on tc couplings eventually derived from these processes are similar to those 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 investigated.
