Tevatron signatures of an R-parity violating supersymmetric theory

We show that an R-parity violating supersymmetric scenario which can accoun t For the atmospheric nu (mu) deficit has testable signals at the Fermilab Tevatron with upgraded energy and luminosity. The explanation of neutrino m asses and maximal nu (mu)-nu (tau), oscillation in terms of bilinear R-viol ating terms in the superpotential associates comparable numbers of muons an d tau's resulting from decays of the lightest neutralino. We show that this should lead to like-sign dimuons and ditaus with substantial rates, in a f orm that separates them from standard model backgrounds and other signals o f supersymmetry. One here also has the possibility of completely reconstruc ting the lightest neutralino. (C) 2000 Published by Elsevier Science B.V.
