Probing R-violating top quark decays at hadron colliders - art. no. 034011

We examine the possibility of observing exotic top quark decays via R-viola ting supersymmetry interactions at the Fermilab Tevatron and CERN LHC. We p resent cross sections for t(t) over bar production followed by the subseque nt decay of either t or (t) over bar via the R-violating interaction while the other undergoes the standard model decay. With suitable kinematic cuts, we find that the exotic decays can possibly be detected over standard mode l backgrounds at the future runs of the Tevatron and LHC, but not at run 1 of the Tevatron due to limited statistics. Discovery limits for R-violating couplings in the top sector are presented.
