W±Z0 and W±γ pair production in νe, pp, and p¯p collisions

Abstract

We augment a previous discussion of the production of pairs of gauge bosons with a study of the reactions $\mathrm{pp}$ and $\overline{p}p\to W{Z}^{0}X or W\gamma X$. As before, these depend upon trilinear boson couplings and the high-energy behavior is controlled by gauge cancellations. In particular, the (hard) photon production is sensitive to the magnetic-moment parameter $\kappa$ for the $W$. We also discuss the related neutrino reactions, $\nu e\to W{Z}^0 or W\gamma$, which may be of interest in very-high-energy cosmic-ray physics.
