Probing R-violating top quark decays at the NLC

Abstract

We examine the possibility of observing exotic top quark decays via $R$-Parity violating SUSY interactions in $e^{+}{e}^{-}$ collisions at \sqrt{s = 500 GeV. We present cross-sections for $t\bar{t}$ production followed by the subsequent decay of either the $t$ or $\overline{t}$ via the $R$-Parity violating interaction while the other undergoes the SM decay. We discuss kinematic cuts that allow the exotic SUSY decays to be detected over standard model backgrounds. Discovery limits for $R$-Parity violating couplings in the top sector are presented assuming an integrated luminosity of $100f{b}^{-1}$.
