Abstract
We suggest that the reactions pp→W±γX and pp¯→W±γX are good candidates for measuring the magnetic moment parameter κ in μW=(e2MW)(1+κ). The angular distribution of the W bosons in pp¯→W±γX is particularly sensitive to this parameter. For the gauge-theory value of κ=1, we have found a peculiar zero in dσ(du¯→W−γ)dcosθ at cosθ=−13, the location of this zero depending on the quark charge through cosθ=−(1+2Qd). A similar zero occurs in dσ(ud¯→W+γ)dcosθ. We can offer no explanation for this behavior.
