John Ellis (physicist)

Theoretical particle physicist (King's College London / CERN Theory Division) who, with Mary K. Gaillard and Dimitri Nanopoulos, wrote the first systematic phenomenological study of the Higgs boson in 1975, and who later wrote a first-person historical account of the Higgs search (arXiv:2611.03315, 2026) presented at CERN's 4th International Symposium on the History of Particle Physics.

Disambiguation: distinct from Alexander John Ellis (1814–1890), the English philologist already in this vault for an unrelated phonetic-notation cluster. No relation; same two given names, different field, different century.

Matters to this vault as a direct historical participant narrating his own work: the 1975 Higgs-phenomenology paper this vault's claim-notes cite is his own, self-narrated in first person — an unusually strong sourcing case for a historical claim, and currently the vault's only entry point into particle-physics history.
