How can Gluon travel at speed of light when it is bound inside a proton or neutron?
mfb said:It doesn't travel for a long distance. But that view is way too classical. Gluons on hadrons do not exist as real particles, so it is meaningless to ask about their speed.
By specifying the gluons in hadrons , does it mean there are gluons that are NOT in hadrons ..?mfb said:The gluons in hadrons: sure.
I think he meant they "aren't anywhere specifically" but when they are in hadrons we know they are there somewhere.Mihail Anghelici said:there are gluons that are NOT in hadrons ..?
They can be in a QCD plasma, or part of hard parton showers before hadronization occurs. In both cases, their properties are not so far away from real particles.Mihail Anghelici said:By specifying the gluons in hadrons , does it mean there are gluons that are NOT in hadrons ..?
vanhees71 said:Well, QCD has the advantage of being in quantitative accordance with all observations. I'm also not so sure that branes linked with multi strings are more "intuitive" than the QFT picture. That's a subjective issue of familiarity with the various theoretical pictures.
String theory is a quantum field theory - with strings instead of "normal" particles. If you think string theory is intuitive, then QFT with the simpler particles of the standard model should be trivial.MacRudi said:although in origin stringtheory came from QT
Isn't that to do with duality? The strings producing gravitation is way more complicated but the duality to SM is identical, isn't it?mfb said:If you think string theory is intuitive, then QFT with the simpler particles of the standard model should be trivial.
You could make up anything and model it with string theory, it provides no bounds to reality...vanhees71 said:Theoretical physics is all about modeling observable facts...
I'm still wondering if gluons are massless by themselves and do travel at c and who's theory has the best answer...MacRudi said:now we are in the psi ontologist and psi phenomelogist debate.

They are massless, in the rare cases where "speed" makes sense their speed is c, and this is true for every theory that is not in conflict with observations.jerromyjon said:I'm still wondering if gluons are massless by themselves and do travel at c and who's theory has the best answer...
The whole thread is over. The initial question has been answered.vanhees71 said:Ok, for me the thread is over...
The speed of light is a fundamental constant in the universe, and it is the maximum speed at which any object can travel. Gluons, as elementary particles, obey the laws of physics and have no rest mass, allowing them to travel at the speed of light.
No, gluons cannot travel faster than the speed of light. According to Einstein's theory of relativity, the speed of light is the ultimate speed limit in the universe. Anything that has mass, like gluons, would require an infinite amount of energy to reach the speed of light, making it impossible.
Gluons are the carriers of the strong nuclear force, which holds together the nucleus of an atom. They interact with other particles at the speed of light through the exchange of virtual gluons. These virtual gluons transfer energy between particles, allowing them to interact with each other.
The speed of light is a fundamental constant in the universe, and it plays a crucial role in the strong nuclear force. The speed of light determines how fast gluons can travel and interact with other particles, making it an integral part of the strong nuclear force.
No, there are no exceptions to gluons traveling at the speed of light. As mentioned earlier, the speed of light is a fundamental constant in the universe, and all particles, including gluons, must obey this limit. Any deviations from the speed of light would contradict our current understanding of physics.
