Double beta decay of Σ-hyperons

We compute the strangeness-conserving double beta decay of Σ- hyperons, which is the only hadronic system that can undergo such decays. We consider both, the lepton number conserving Σ- → Σ+e-e-νν (ββΣ2ν) and the lepton number violating Σ- → Σ+e-e- (ββΣ0ν) modes. The branching ratios of these ββ dec...
