Gauge group choice

  1. Dec 27, 2011 #1

    I have been assuming something I never took the time to prove because it is beyond my scope so to speak. But I am on the path, rest assured.

    My question is, is it possible to describe correctly say, the color force, using a different gauge group, regardless of the difficulty? That is for example, is it possible to describe the color force, or the weak force using the gauge group U(1) regardless of the perhaps extreme difficulty?

    All SU(N) gauge groups have similar properties, especially they produce confinement (only if unbroken; see Higgs mechanisms in el.-weak theory w/o confinement). U(1) always has long-range photons, so there is no way to generate short-range confinement from U(1).
