According to the Wikipedia article on color confinement "The current theory is that confinement is due to the force-carrying gluons having color charge"color confinement:
The current theory is that confinement is due to the force-carrying gluons having color charge [...],
i.e. because the gauge group is non-abelian. But that is equally true for the weak force. Does that mean that above the electroweak scale we should expect to find stuff like electrons and neutrinos confined to meson-like states?
