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

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.
Danh từ
any baryon that is not a nucleon; unstable particle with mass greater than a neutron
