Gluons Definition and 68 Threads

Hi, i am kind stuck on this question as i don't know what equation to use. doesn't seem to be in any books. By considering possible interactions between protons and neutrons, determine the minimum number of charge states of yukawa's particle. Also why is the interquark force of finite...

How many gluons are needed to bind the 3 quarks in a proton?

How many gluons are needed to bind the 3 quarks in a proton?

I read this from wiki, I don't trust that site a lot. Is this true? can someone elaborate on this?

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...

How to form a J^{PC} = 1^{--} state with only gluons? Two gluons? Three ? How do the P, C, J values work?

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, - James

photons and gluons have the same mass, charge, width and GeV? so what tells them apart?

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...

Can gluons exist outside of their association with quarks? If so has any experiment shown it and what has it shown?

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
