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

Comparison with constituent quark models identifies four discriminants: |μ|≳3μ_N in spin-1/2; sign of μ for [su][uc]c̄ in spin-3/2; non-zero Q (vanishes in S-wave molecules); and the Q-O sign correlation, probing 1/m_q weighting.

C2weakest assumption

The chosen diquark-diquark-antiquark interpolating currents couple dominantly to the physical pentaquark states with negligible contamination from other resonances or continuum states.

C3one line summary

Electromagnetic moments of Σ-type pentaquarks are computed via light-cone sum rules, yielding flavor-sensitive magnetic dipoles, quadrupoles, and octupoles that distinguish diquark types and rule out S-wave molecules.
