Discussion Overview

The discussion centers on the properties and relationships of quarks, particularly the up quark and down quark, and their implications for matter-antimatter symmetry. Participants explore theoretical models, including composite structures and the nature of quark charges, while considering experimental insights related to matter and antimatter interactions.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Mathematical reasoning

Main Points Raised

  • Some participants propose that an up quark could be composed of two antidown quarks, suggesting energy release in this process.
  • Others discuss the idea that the top quark may be a condensate of a different particle, not another quark, and question its relation to matter-antimatter symmetry.
  • One participant raises a question about whether two color charges can combine to form a single color charge by releasing energy that carries a second color charge.
  • It is noted that quarks are defined by multiple properties, including color, electric charge, and weak isospin, indicating that a different type of particle may be necessary for certain models.
  • There is a discussion about the implications of fractional charges of quarks, with one participant suggesting that the configuration of these charges may relate to the dominance of matter over antimatter in the universe.
  • Experiments at CERN are mentioned as potentially revealing insights into the nature of matter and antimatter interactions, particularly regarding the annihilation spectrum.

Areas of Agreement / Disagreement

Participants express multiple competing views regarding the composition of quarks and the implications for matter-antimatter symmetry. The discussion remains unresolved, with no consensus on the proposed models or interpretations.

Contextual Notes

Limitations include assumptions about the nature of quark composition and the dependence on theoretical models that may not be universally accepted. The discussion also highlights unresolved mathematical aspects related to charge configurations.

up quark and down quark

An up quark has a smaller mass than a down quark.
Is it possible that an up quark is made from 2 antidowns with energy being released?

Composite models, techicolor, topcolor etc. It is assumed that the top quark is a condensate of some other particle (not other quark). A lot of work done. No idea about how it relates to matter/antimatter symmetry (antimatter is always likely to anhiquilate against matter).
 
ARIVERO:

SONTAG:
So two colour charges can't come together and form one colour charge
by releasing some energy that carries a second colour charge?
 
well, quarks are not only defined by colour, also electric charge and weak isospin. So another kind of particle is required. This is called techicolor.

An up Quark has more fractional Charge than a Down Quark..
UP 2/3 charge Down 1/3 Charge

2/3..'two thirds' of a down composite Quark..does not equal..2/3s of an Up Quark.

Matter prevails over Anti-Matter..there are I believe experiments underway at CERN:http://www.exploratorium.edu/origins/cern/ideas/antimatter.html
which are hoping to uncover if the 1/3 fractional charge of ordinary Protons, represents 'Negative' matter, and it may be that the Anti-Matter Anhilations, will show this to be so?

For instance the Matter >>Antimatter anhilation spectrum, might reveal the energy released to be 'less or more' than the reversed interaction of Anti-Matter .>> Matter interactions.

The fact that fractional charge has the configuration it has 1/3 + 2/3..is a remnant of early Universe interaction..it does not balance out..for instance if Quarks had a Fractional Charge of 1/4 +1/4..this would be perfectly symmetrical..and matter could not prevail over Anti-Matter?
