Are messages of R-parity violating supersymmetry hidden within top quark signals?

In an R-parity nonconserving supersymmetric theory, the lighter stop can do minantly decay into b mu and b tau if R-parity breaking has to explain the neutrino mass and mixing pattern suggested by the data on atmospheric muon neutrinos. This should give rise to dilepton + dijet and single - lepton jets, signals identical with those of the top quark at the Fermilab Tevatro n. One can thus constrain the stop parameter space using the current top se arch data and can similarly look for the first signals of supersymmetry at the upgraded runs of the Tevatron.
