Single Idea 21142

[filed under theme 27. Natural Reality / B. Modern Physics / 3. Chromodynamics / b. Quarks ]

Full Idea

Classifying hadrons according to charge, strangeness and spin revealed patterns of eight and ten particles (SU(3) symmetery). The mathematics then showed that these are built from a basic group of only three members.

Gist of Idea

Classifying hadrons revealed two symmetry patterns, produced by three basic elements
