| | Oh yeah, I just remembered something else. Yeah the reason for color confinement is that it does that an infinite amount of energy to set up a color charge field that can act globally. So yeah, you are right about needing the infinite energy part. The strange reason for this is that gluons can multiply by themselves. For quantum electrodynamics, the virtual photon which is the interaction particle that's responsible for the effects of electrostatic and magnetic forces can only interact with other charged particles at any one time. You have to take a look at the Feynman graph vertex for QED to see this. But the gluon, the photon counterpart for QCD can interact with other gluons, it has the three and four gluon vertex. This allows it to sorta multiply without limit, figuratively speaking. The classical flux for QCD from an isolated color charge can get bigger and is not constant. Confinement is needed to contain this flux within a small space, giving it a finite energy for the QCD field. |
