4.8 Probe for R-violating top quark decays

In this section we review the possibility of observing exotic top quark decays via R-Parity violating SUSY interactions in e+e- collisions at $\sqrt{s}= 500~GeV$ [57]. 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 $100\,fb^{-1}$.
