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

These results expand the spectrum of baryon excited states and provide crucial experimental support for understanding non-perturbative QCD and resolving the ``missing baryon resonances'' problem.

C2weakest assumption

The observed peaks in mass spectra are interpreted as genuine new resonance states rather than background fluctuations, interference effects, or misidentified known states.

C3one line summary

BESIII reports discoveries of multiple new excited light baryon states from high-statistics data, expanding the known spectrum and supporting non-perturbative QCD studies.
