The Implications of $\bar{\nu}_e e^-\to W^-\gamma$ for the Detection of High-Energy $\bar{\nu}_e$

We discuss some motivations for detecting high-energy neutrinos through the pure electroweak processes such as $\bar{\nu}_e e^-\to W^- $ and $\bar{\nu}_e e^-\to W^-\gamma$. We argue that the latter process can be viewed as an enhancement to the former one. The event-rate enhancement is estimated.
