Sometimes, color confinement is explained loosely by stating that the gauge group of QCD, namely SU(3), is non-abelian gauge group and, therefore, tends to form narrow "flux tubes" through which the "efective force" does not decrease with distance.

However, this absolutely informal explanation leaves out the key factor (whatever would be). Since, for example, the Weinberg–Salam theory (WST) describing weak interaction is also based on a gauge theory with the non-abelian group SU(2), one would think that it should also form narrow flux tubes, that would prevent any "weak charge" from being observed unconfined.

My question is: What is the ingredient that makes QCD lead to color confinement, but WST does not entail weak charge confinement?

    You may, and do, understand both weak and strong interactions in terms of a non-singlet state description and a singlet state description, above a characteristic scale and below it, respectively. For the strong interactions, the scale is a fraction of a GeV, Λ; for the weak ones, once you appreciate Susskind's complementarity, touched upon in the linked question, it is a quarter of a TeV. – Cosmas Zachos Jul 24 '22 at 13:43
