Quark confinement and meson confinement

Quote Quote by not-even-phys View Post
Thank you. I wish you could clarify "The color forces don't let a color-charged particle to live isolated". I understand what this means, but how this happens actually? If the quark that belongs to the meson is attracted to the proton by the strong forces - why this attraction doesn't hold him inside the proton?
I'm not an expert in this field, however... Maybe it should be clearer if I say that the initial and final states of a scattering process must be color neutral; during the scattering process the quarks can mix up, as the are confined pratically in the same place. Then they can split, to the final states, only in color-neutral "groups".

And that's why you happen to see only color-neutral particles. Can you understand now? (If you don't, probably is due to my lack of knowledge in this field ;-) )
