Description

From a retroactive data analysis, we derive the first upper bound on a |ΔL|=2 hyperon decay: B(Ξ-→pμ-μ-)<3.7x10-4 (90% C.L.). We also comment on the decay Σ-→pμ-μ- and |ΔL|=2 decays of charmed and b baryons, in particular, Ξc+→Ξ-μ-μ-. Finally, rough upper limits are given on B(Σ-→pμ-e-) and B(Ξ-→pμ-e-)
