Discussion Overview

The discussion revolves around the existence of anti-gluons and the implications for fundamental particles in the Standard Model. Participants explore the nature of gluons, their properties, and the search for other particles like the graviton, touching on theoretical and experimental aspects.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants propose that every fundamental particle should have an anti-counterpart, questioning whether anti-gluons exist.
  • One participant states that gluons are their own antiparticles, carrying both a color and an anti-color, providing an example of how this works.
  • There is a suggestion that the LHC will eventually search for the graviton after confirming the Higgs boson, with some participants expressing interest in the necessity of proving the existence of gravitons.
  • A participant raises a question about the differences between two states in the gluon octet, indicating a technical inquiry into gluon properties.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the existence of anti-gluons, and multiple views regarding the properties of gluons and the search for gravitons remain present.

Contextual Notes

Some claims depend on specific definitions of particles and their properties, and there are unresolved questions about the implications of the LHC findings on future particle searches.

Since every fundamental particle in the Standard Model should have it's anti-counterpart?

Also, after the LHC has (if they will ever will) found the Higgs boson, will they start looking for the graviton?

Michio, Good to hear from you. Gluons are their own antiparticles. Each gluon carries a color and an anti-color. So a particular gluon could be for example, labelled red anti-blue. Its antiparticle would then be another gluon labelled blue anti-red.

We expect to have enough data by the end of 2012 to tell whether the signal at 125 GeV is really the Higgs boson. Assuming it does, there will be a great amount of work done to study it and determine if it really has all the expected properties. Beyond the Higgs, the LHC will hopefully provide evidence either for or against the existence of supersymmetry at the TeV scale.
 
What about gravitons? Must we attempt to prove their existence?
 
Also, what is the difference between:

They represent 2 states in the gluon octet.
