The theoretical mechanism, introduced into particle physics in 1964, by
which gauge vector bosons acquire mass through spontaneous breaking of gauge
symmetry — the piece of the Standard Model that lets the weak force's carrier
particles be massive without breaking the theory's gauge invariance.
Discovered independently by three groups in 1964 (Englert-Brout, Higgs,
Guralnik-Hagen-Kibble); confirmed experimentally via the discovery of the
associated massive scalar particle (the Higgs boson) at CERN in 2012.

Matters to this vault as the organizing concept of its first particle-physics
cluster and a clean, Tier-1-sourced instance of the vault's recurring
multiple-discovery and naming-vs-priority themes: the mechanism's substance
was found three times over, but it is popularly named for the one group that
also predicted its associated particle. John Ellis's own 2026 paper titles
itself around "the EBH mechanism" specifically to push back on the
Higgs-only naming convention — a live naming dispute, not a settled one.
