Multilepton production via top flavour-changing neutral couplings at the CERN LHC

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.

30 pages, 23 PS figures. Uses epsfig.sty and elsart.sty. Added some references and corrected some typos. Added more comments about statistics. Using elsart.sty reduces the size to 30 pages. Published in Nucl. Phys. B
