Well, this is not what i thought i understand... I've read in wikipedia that asymptotic freedom means that strong force is weaker when the distance is smaller, and it is not related to the "high energies". Furthermore, the fact that this force gets stronger when quarks are far from each other...
Thanks. I understand that the final state (of separated proton and meson) is "legal", but do not really understand why the forces inside the proton let the quarks move into this final state. I've read that the forces between the quarks are very strong, and just can't understand why they do not...
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...
We know that when photon/electron/muon/proton hit another proton then many types of mesons exit the proton. Why these mesons are not confined inside the proton, and single quarks are?
Thanks, and sorry if this is a stupid question... I couldn't find an answer in the literature.
