The ΔI = 1/2 rule: first-principles dynamical origin of octet enhancement in nonleptonic kaon and hyperon decays
The colour-singlet null-plane theory of hadrons: complete algebra, representation, stress-energy tensor, and confinement in QCD (Fritzsch–Gell-Mann 1972)
Constructive completion of the multiplicity-based maximum entropy principle for general path-dependent processes
Principled selection and uniqueness of maximally refined quasiclassical realms in decoherent-histories quantum mechanics
Completing the Gell-Mann–Ne'eman classification of current-generated algebras: parity implementations, exceptional factors, minimality, and semisimplicity
Elementary or dynamically generated? The surviving open core of the Gell-Mann–Zachariasen vector-meson account of electromagnetic form factors
Quantum and structural viability of scalar-induced spacetime compactification (the Gell-Mann-Zwiebach sigma-model mechanism)
Realizing Gell-Mann-Hartle strong decoherence in concrete models: adaptive branch-dependent coarse grainings, environment factorization, record-formation timescales, and branch density-matrix diagonality
Physically acceptable representations of the local current algebra at infinite momentum and the excitation structure of the hadron spectrum
