An unstable subatomic particle classified as a baryon, heavier than the neutron and proton.
- ‘The baryon classification took on new members, including particles more massive than the proton called hyperons.’
- ‘We now call these particles ‘kaons’ and ‘lambda hyperons,’ but at the time they were simple ‘strange particles.’’
- ‘Then the integer-spin-drive wake of a passing scout ship assigned to trail the passing starcruiser disrupted Faulk's hyperon multiplet enhancer.’
- ‘The lightest particles were named leptons, those with medium mass, mesons, heavier particles were called baryons, and the heaviest particles of all, hyperons.’
1950s: from hyper- beyond, over + -on.
