Search for \(ΔS=2\) nonleptonic hyperon decays \(Ω^-\toΣ^{0}π^{-}\) and \(Ω^-\to nK^{-}\)

By Besiii Collaboration and others
Using \((27.12 \pm 0.14) \times 10^{8}\) \(\psi(3686)\) events collected by the BESIII detector at the center-of-mass energy of \(\sqrt{s} = 3.686\) GeV, we search for the first time for two nonleptonic hyperon decays that change strangeness by two units, \(\Omega^-\to\Sigma^{0}\pi^-\) and \(\Omega^-\to nK^{-}\). No significant signal is observed. The upper... Show more
