[QUOTE="vanhees71, post: 5890398, member: 260864"] The Glashow-Salam-Weinberg theory is not asymptotically free. There's a U(1) in the gauge group and also it's Higgsed. I'm not certain anymore, what's the precise statement but if I remember right, one can show that for a wide range of Higgsed local gauge symmetries the resulting models are not asymptotically free, even if there are no U(1)'s are in the gauge group: Higgs phenomena in asymptotically free gauge theories T.
