Probing $WW\gamma$ Couplings from ${\sigma }_{tot}(W)\mathrm{/}{\sigma }_{tot}(Z)$ in High Energy ep Collisions

We investigate the sensitivity of total cross sections of $e+p \rightarrow W,Z$toCP-conservingnon-standard$WW\gamma$ couplings. We include all the important production mechanisms and study the dependence of the total $W$ cross sections on the anomalous $WW\gamma$ couplings, $\kappa$ and $\lambda$. We argue that the ratio of $W$ and $Z$ production cross sections is particularly well suited, being relatively insensitive to uncertainties in the theoretical and experimental parameters.
