Wilson loop is not an element of $\mathrm{SU}(3)$ in color deconfinement
The center symmetry in QCD comes from the
$$a\ \mathcal{P}\mathrm{exp}\left(ig_s \int_C dx^\mu \ A_\mu(x)\right) a^{-1} = \mathcal{P}\mathrm{exp}\left(ig_s \int_C dx^\mu \ A_\mu(x)\right),$$
where $C$ ...

Permitted bound states in extended QCD color group $SU(4)$
I'm very much curious about the possible quark combinations to form bound states in $SU(4)$ QCD.
We already know Wilson has proven that only colorless combinations can arise in $SU(3)$ of these ...

The distinctions between $\mathrm{U}(1)$ and $\mathrm{SU}(3)$ massless bosons
The force carrier particles that mediate the electromagnetic, weak, and strong interactions are called gauge bosons. It is known that the gauge bosons in EM force and strong force are both massless.
