Examples

“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.”
