Magnetic moments of compositeWbosons

We have calculated the anomalous magnetic moment of the W boson (${\kappa }_W$) in a class of nonrelativistic composite models. We have found, for example, that in a model with only scalar preons, ${\kappa }_W$≥3. For the case of two spin-(1/2) preons with L=0 and equal masses we find the very surprising result that ${\kappa }_W$=1, the standard gauge-theory value. There are four possible preon spin states. We have found a general expression for ${\kappa }_W$ for any linear combination of these states. A range of allowed values for ${\kappa }_W$ has been obtained. We also discuss the quadrupole moment for a composite W.
