English

Pronunciation

• IPA^(key):/ˈhaɪpəɹɒn/

Noun

hyperon(pluralhyperons)

1. (physics)Anybaryon(a three-quark particle) with a non-zerostrangeness(i.e., whose composition includes one or morestrangeoranti-strange quarks).
   • 1965,Richard Henry Dalitz,Nuclear Interactions of theHyperons,page 1:

     The knownhyperonsand their properties are listed in Table I of the companion lectures on Strange Particles. Most of thesehyperonshave lifetimes of the order of 10^-10sec, with the exception of the Σ⁰-hyperonwhose electromagnetic decay has an exceedingly short lifetime.

   • 2000,Norman K. Glendenning,Compact Stars: Nuclear Physics, Particle Physics, and General Relativity‎^[1],page264:

     What is particularly noticeable is the steep rise inhyperonpopulations as the limiting mass is approached.

   • 2001,M.K. Sundaresan,Handbook of Particle Physics‎^[2],page21:

     The properties of the Λ⁰hyperonand of theΚ⁰were more precisely determined. The charged counterparts of the neutralΚparticle were also found as well as the charged Σhyperonsand their neutral counterpart.
