In May 2023 we began a rather earnest effort to begin to categorize all the most-commonly hypothetical particles and the scholar-scientist who was focused on it.
The first hypothetical particle we ever mentioned in our work was the preon. It is on line 46 of our first chart of Planck Length and its multiples. We had learned a little about Abdus Salam and Jogesh Pati. For our initial understanding, we started with Wikipedia. There they say,
“In particle physics, preons are point particles, conceived of as sub-components of quarks and leptons. The word was coined by Jogesh Pati and Abdus Salam, in 1974. Interest in preon models peaked in the 1980s but has slowed, as the Standard Model of particle physics continues to describe physics mostly successfully, and no direct experimental evidence for lepton and quark compositeness has been found. Preons come in four varieties, plus, anti-plus, zero and anti-zero. W bosons have six preons, and quarks and leptons have only three.”
More to come… (1) The illusion of point particles, (2) The making of infinitesimal composites
