Talk:Gluon

What does it mean to divide colors by sqrt(3)? Is that a number? In what units? What is the numeric value of a "state"?

I'm not an expert, or even a physicist, but (as I understand it) the values describe the chances of a gluon having the combination of those 'colors' (they're not really colors, just convenient labels). If you want the chances of the combination to come out between zero and one (that's required) you have to normalize them. Hence you device by the sqrt(1^2+1^2+1^2)=sqrt(3). It's basically the Pythagorean theorem in disguise. Ask an actual physicist for a better answer. Kleuske (talk) 10:15, 21 October 2021 (UTC)

The value of the color charge is a complex unit vector in a three-dimensional complex vector space (a complex three-dimensional Hilbert space). The eigenvectors that span the space is the three colors of the color charge (i.e. the basis axes X, Y, Z of this space are labeled "red", "green", "blue", or in physics-speak $|{\text{red}}\rangle ,|{\text{green}}\rangle ,|{\text{blue}}\rangle$ where the $|\cdot \rangle$ is called a "ket", from the bra-ket notation.) These color charge vectors define the probabilities for measurement of the color charge. The sqrt(3) term is for normalization the quantum state, so it remains a unit vector (see unitarity). The 1/sqrt(3) factor is the probability amplitude of each of the possible outcomes of this three-level quantum state. · · · Omnissiahs hierophant (talk) 18:57, 16 December 2021 (UTC)

Interaction with gravity?

Why don't we list gravity under "Interactions" in the infobox? Or maybe more precisely, why do we list gravity as an interaction for some particles (for example quarks and photons) but not for all particles? I thought all particles were affected by gravity in the sense that all of them follow geodesics, and that all particles had a gravitational effect on other particles, since all particles have an energy and energy curves space, which gives rise to orbits that look like they are affected by gravity. —Kri (talk) 17:58, 16 December 2021 (UTC)

Maybe no one has seen a gluon interact with gravity. No experimental data. We should avoid making stuff up just because it makes sense. What if gluons don't interact with gravity? — Preceding unsigned comment added by 98.128.172.242 (talk) 12:01, 17 December 2021 (UTC)

Antigluons?

In the following:

• red–antired ($r{\bar {r}}$), red–antigreen ($r{\bar {g}}$), red–antiblue ($r{\bar {b}}$)
• green–antired ($g{\bar {r}}$), green–antigreen ($g{\bar {g}}$), green–antiblue ($g{\bar {b}}$)
• blue–antired ($b{\bar {r}}$), blue–antigreen ($b{\bar {g}}$), blue–antiblue ($b{\bar {b}}$)

the following appear to be their own antiparticles:

• red–antired ($r{\bar {r}}$), green–antigreen ($g{\bar {g}}$), blue–antiblue ($b{\bar {b}}$)

while the following appear to be particle/antiparticle pairs:

• red–antigreen ($r{\bar {g}}$), green–antired ($g{\bar {r}}$)
• red–antiblue ($r{\bar {b}}$), blue–antired ($b{\bar {r}}$)
• green–antiblue ($g{\bar {b}}$), blue–antigreen ($b{\bar {g}}$)

Is that a correct interpretation? If that's the case for the particle/antiparticle pairs above, then that would be a case of bosons having antiparticles (or is it only fermions that could have antiparticles?)! 137.82.118.58 (talk) 00:13, 9 June 2023 (UTC)

Question, Bion?

Is it a bion? — Preceding unsigned comment added by 203.211.104.191 (talk) 06:58, 16 October 2023 (UTC)

article level not appropriate for general encylopedia

wiki is supposed to be a general encyclopedia, accessible to the average person

I don't know what the average person is, but this article is written at way too high a level, it’s more appropriate for a college senior majoring on physics — Preceding unsigned comment added by 50.245.17.105 (talk) 20:38, 1 November 2023 (UTC)
