A gluon () is an elementary particle that acts as the exchange particle (or gauge boson) for the strong force between quarks. It is analogous to the exchange of photons in the electromagnetic force between two charged particles. In layman's terms, they "glue" quarks together, forming hadrons such as protons and neutrons.
In technical terms, gluons are vector gauge bosons that mediate strong interactions of quarks in quantum chromodynamics (QCD). Gluons themselves carry the color charge of the strong interaction. This is unlike the photon, which mediates the electromagnetic interaction but lacks an electric charge. Gluons therefore participate in the strong interaction in addition to mediating it, making QCD significantly harder to analyze than quantum electrodynamics (QED).
hey , just wondering about gluons :
red - anti red
red - anti blue
red - anti green
blue - anti red
blue - anti blue
blue - anti green
green - anti red
green - anti blue
green - anti green
Our common sense tells us there's 9 , but in reality there's 8, how come ?
I have already...
There are said to be eight gluons, and I understand the reasoning, but I cannot determine for certain if this is a purely theoretical position or is it possible to observe gluons by experiment?
My understanding is that the machines needed to separate and observe gluons are still under construction.
Greetings,
I found a puzzling reference in my EP-course, that basically says :
"Gluon cary a dual charge, one colour and one anticolour. This means one can have 3²=9 combinations."
So far, so good. But then :
"We have to substract one colourless combination. This leaves us with 8...
I;ve heard 2 different things, and onw says that the strong force is mediated by the gluon, but also, I've also heard that it is mediated by pions. The strong force, AFAIK, is actually caused when the 3 quarks in a hadron, continually exchange gluons with each other. And if a red quark, emits a...
Under what circumstances could the colour force ( or the strong residual force) become repulsive between quarks? I've heard that changing the spin of a force carrier can in principle make a force repulsive when it was previously attractive.If gluons exchanged between quarks became fermions with...
Gluons are dark energy.
They emit gravitons and these collide with photons and cause them to lose
energy - as yet more gravitons - and redshift.
As the photons travel through space they get longer wavelengths and gravitons of longer wavelength (emitted by gluons) collide with them so
that...
Hi,
We know that the gluons rest mass is 0.On the other hand we also know that the u and d quarks that compose the nucleons are responsible for the 50% of the nycleons mass for the rest 50% are responsible the gluons!
Why the massless gluons “gain” mass when they are inside the nycleons...
Is anyone able to tell me what happens when a down quark emits a gluon which subsequently decays?
It’s for my studies, so only hints please
Many thanks in advance,

in the atom if you try to look into a neutron for example you would see the quark/gluon triangle but if you use a wave length to spot it won't the uncertainty princable make the particles change there location and so disrupt the nucleus and rips it apart. is that possible?
Question 2
is...
I’ve been trying to find specifics about quarks and gluons, and it seems like not a lot is known.
If I’ve got things right Up quarks have a speculated mass between 1.5 and 4.5 MeV, and Down quarks a speculated mass of between 5 and 8.5 MeV. Gluons are considered to be massless. A proton is...
Is my understanding correct that gluons are the force carrier particle of the strong nuclear force?
Do gluons hold together quarks? Or do gluons hold together atomic nuclei?
Thanks,
Glenn
