What is the latest on the periodic table of particles?

Click For Summary

Discussion Overview

The discussion revolves around the concept of a periodic table of particles, exploring its current status, the classification of fundamental particles, and the theoretical implications of their arrangement. Participants inquire about the existence and understanding of such a table, referencing historical classifications and current theories.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant questions the validity of referring to a periodic table for particles, suggesting that having only three generations of particles does not justify the term "periodic."
  • Another participant notes that while there is a repeating structure among leptons and quarks, the reason for the existence of three generations remains unknown, and there is no evidence supporting the idea that these particles are composite.
  • A historical reference is made to Gell-Mann's Eightfold Way, which classifies hadrons based on symmetrical properties, suggesting it may be relevant to the discussion of particle classification.
  • Participants share links to external resources that provide further information on the classification of particles and the standard model.

Areas of Agreement / Disagreement

Participants express differing views on the appropriateness of the term "periodic table" for particles, with some questioning its relevance given the limited number of generations. There is no consensus on the reasons behind the observed generations of fundamental particles or their potential composite nature.

Contextual Notes

Participants acknowledge the challenges in obtaining peer-reviewed research and the limitations of amateur theories in the field. The discussion reflects ongoing uncertainties in particle physics and the classification of fundamental particles.

I've heard that there's a periodic tables of particles, I've searched the net but have yielded little results. Is it still in the works? or is it out yet?

Call it periodic table is more like a joke, considering the few numbers of particles. There are 3 generations, would you say you definitely have observed a periodic signal in only 3 periods ? Besides, when we talk about Mendeleiev periodic table, we know where the structure comes from, we understand what is meant here by periodic. The reason why the atomic properties are periodic is traced back to the electronic strucure of atoms. In the case of particles, we contemplate 3 generations, without (yet) having found a satisfactory reason for those 3 generations. I hope you can find useful information here :

This is the clearest statement by an accepted authority, that explains current beliefs that I have found to date.

Three and only three?
It is not yet known why there should be successive "families" or "generations" of fundamental particles in this way. The fact that both the leptons and the quarks are laid out in a repeating structure, suggests to some that these particles may themselves be composite, made up of yet smaller entities the way that nuclei are made up of protons and neutrons, while protons and neutrons are made up of quarks.
To date there is no evidence for this. A 1996 suggestion of quark structure by the CDF collaboration, discoverers of the top quark, has more recently appeared to be something more prosaic.
There do seem to be only three generations


I am sorry I cannot be more helpful as this is my speciality, but amatuer theories are not permitted on this PF. My work has been debated by two colleges of higher education, one scientific debating group and I once received a correction from a leading astrophysicist who's work I had quoted; but I cannot get it peer reviewed. These are problems all researchers have to face, but the struggle is its own reward.
Enjoy your research

In 1961 Gell-Mann classified hadrons in a theory called Eightfold Way. Perhaps is what you re searching
http://zyx.org/EIGHTFOLD.html
"Eightfold Way,
classification of subatomic particles known as hadrons into groups on the basis of their symmetrical properties, the number of members of each group being 1, 8 (most frequently), 10, or 27."

This?

This is a simplified one, with only a few, a table of particles... standard model...

Scroll down when taken to http://wc0.worldcrossing.com/WebX?50@87.uWONcZfwCDg.0@.1ddf905d and you will find a good explanation and a couple of links that will really help.
