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

Abstract

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.
