The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The BESIII experiment leverages an unprecedented dataset of over 10^10 J/ψ events and 2.7×10^9 ψ(2S) events to push the sensitivity of charmonium weak decay searches and establish the latest and most stringent upper limits on various semi-leptonic, non-leptonic, and FCNC channels.

C2weakest assumption

The review assumes that the published BESIII analyses correctly account for all systematic uncertainties and that the quoted upper limits accurately reflect the experimental sensitivity without overlooked backgrounds or efficiency mis-estimates.

C3one line summary

BESIII has set the most stringent experimental upper limits on semi-leptonic, non-leptonic, and FCNC weak decays of J/ψ and ψ(2S) charmonium using its large datasets.
