Tevatron signatures of an R-parity violating supersymmetric theory

We show that an R-parity violating supersymmetric scenario which can account For the atmospheric nu (mu) deficit has testable signals at the Fermilab Tevatron with upgraded energy and luminosity. The explanation of neutrino masses and maximal nu (mu)-nu (tau), oscillation in terms of bilinear R-violating terms in the superpotential associates comparable numbers of muons and 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 form that separates them from standard model backgrounds and other signals of supersymmetry. One here also has the possibility of completely reconstructing the lightest neutralino. (C) 2000 Published by Elsevier Science B.V.
