Photoproduction of charged intermediate vector bosons

Abstract

We consider the photoproduction of charged intermediate vector bosons $W^{+}$ or $W^{-}$ with an arbitrary anomalous magnetic moment $\frac{\kappa e}{2M_W}$. The cross sections at high energies are shown to increase logarithmically with $\frac{s}{M_W^2}$ except for the case $\kappa =1\mathrm{}$, where a constant cross section equal to $\sqrt{2}\alpha G_F$ is reached. The deep-inelastic photoproduction of $W^{\pm }$ is calculated in a quark-parton model and we present numerical results for the total and the differential cross sections.
