Abstract

Models with a nonuniversal Z^\ensuremath' exhibit in general flavor changing neutral currents at tree-level. When the Z^\ensuremath' couplings favor the third generation, flavor changing transitions of the form Z^\ensuremath'tc and Z^\ensuremath'tu could be large enough to be observable at the LHC. In this paper we explore this possibility using the associated production of a single top-quark with the Z^\ensuremath' and find that integrated luminosities of a few hundred fb^\ensuremath-1 are necessary to probe the interesting region of parameter space.
