W magnetic moment in electroweak mixing and composite models and radiation zeros in qjq» j→ W

The same experimental and theoretical constraints that are used to set limits on the masses of the weak bosons in the composite-model versions of electroweak mixing models are used to bound the magnetic-moment parameter of the W. We find in general electroweak mixing schemes, ones with additional heavy isospin-1 bosons (W), that off-diagonal weak-boson electromagnetic interactions (WW vertices) are allowed. The cross section for the process qiq»jW, which has been suggested as the best way to measure the W moments, is generalized to include the effects of these off-diagonal couplings as well as arbitrary and independent W magnetic dipole and electric quadrupole moments.
