Implications of $\bar{\hat{I}}{½}_e{e}^{-}\to W^{-}{\hat{I}}^3$ for high-energy $\bar{\hat{I}}{½}_e$ observation

Abstract

Absorption of high-energy $\bar{\hat{I}}{½}_e$ over electrons above the W boson production threshold is reexamined. It is pointed out that, in the case of photon emissions along the direction of incident high-energy $\bar{\hat{I}}{½}_e$, the kinematically allowed average energy carried by the final state hard photon can be $\le 1$ of the incident $\bar{\hat{I}}{½}_e$ energy above the W boson production threshold. The differential energy spectrum for the final state hard photon is calculated. We also discuss implications of our results for the prospective search of high-energy $\bar{\hat{I}}{½}_e$ through this final state hard photon.
