First, the coupling constant of the strong force can be computed.. does it mean it should also (ought to be) for the electroweak?(adsbygoogle = window.adsbygoogle || []).push({});

Also U(1) is not asymptotically free but electroweak SU(2)xU(1) is asymptotically free.. why is SU(2)xU(1) asymptotically free?
