“…This allows to tag hyperon (antihyperon) production in the process e + e − → J/ψ → B B by using common decay mode of B( B) and to investigate absolute branching ratio of rare decays modes of the B(B). First measurements and searches using this method have been performed by BESIII [280,[413][414][415].…”

“…[354] may be improved upon using several published results and some preliminary simulations. For example, in the search for the lepton-numberviolating Σ − decays with 1.3 × 10 9 J/ψ events [413], the actual obtained experimental upper limits are B(Σ − → pe − e − ) < 6.7 × 10 −5 and B(Σ − → Σ + X) < 1.2 × 10 −4 , respectively. Given that this analysis is almost background-free, one would expect from scaling naively with the statistics the bounds B(Σ − → pe − e − ) < 8.7 × 10 −6 and B(Σ − → Σ + X) < 1.6 × 10 −5 from the 10 10 J/ψ sample.…”

Rare meson decays are among the most sensitive probes of both heavy and light new physics. Among them, new physics searches using kaons benefit from their small total decay widths and the availability of very large datasets. On the other hand, useful complementary information is provided by hyperon decay measurements. We summarize the relevant phenomenological models and the status of the searches in a comprehensive list of kaon and hyperon decay channels. We identify new search strategies for under-explored signatures, and demonstrate that the improved sensitivities from current and nextgeneration experiments could lead to a qualitative leap in the exploration of light dark sectors.
