hyperon

See also: hypéron

English

Noun

hyperon (plural hyperons)

1. (physics) Any baryon with a non-zero strangeness (i.e., whose composition includes one or more strange or anti-strange quarks).
   • 1965, Richard Henry Dalitz, Nuclear Interactions of the Hyperons, page 1,

     The known hyperons and their properties are listed in Table I of the companion lectures on Strange Particles. Most of these hyperons have lifetimes of the order of 10^-10 sec, with the exception of the Σ⁰-hyperon whose electromagnetic decay has an exceedingly short lifetime.

   • 2000, Norman K. Glendenning, Compact Stars: Nuclear Physics, Particle Physics, and General Relativity‎^[1], page 264:

     What is particularly noticeable is the steep rise in hyperon populations as the limiting mass is approached.

   • 2001, M.K. Sundaresan, Handbook of Particle Physics‎^[2], page 21:

     The properties of the Λ⁰ hyperon and of the Κ⁰ were more precisely determined. The charged counterparts of the neutral Κ particle were also found as well as the charged Σ hyperons and their neutral counterpart.
