Title: Supersymmetry-induced flavor-changing neutral-current top-quark processes at the CERN Large Hadron Collider

Abstract

We systematically calculate various flavor-changing neutral-current top-quark processes induced by supersymmetry at the Large Hadron Collider, which include five decay modes and six production channels. To reveal the characteristics of these processes, we first compare the dependence of the rates for these channels on the relevant supersymmetric parameters, then we scan the whole parameter space to find their maximal rates, including all the direct and indirect current experimental constraints on the scharm-stop flavor mixings. We find that, under all these constraints, only a few channels, through cg{yields}t at parton level and t{yields}ch, may be observable at the Large Hadron Collider.
