ν¯eeannihilations

We study the production of leptons, hadrons, gauge bosons, and Higgs particles in ${\overline{\nu }}_{e}e$ annihilation covering a large energy range. Specific final states include ${\overline{\nu }}_{e}e$, ${\overline{\nu }}_{\mu }\mu$, ${\overline{\nu }}_{\tau }\tau$, ${\pi }^{-}{\pi }^0$, ${\rho }^{-}$, $F^{*-}$, and quark-antiquark (jet) pairs. Beyond the $W^{-}$ pole we compare $W^{-}\gamma$, $W^{-}{Z}^0$, and $W^{-}H$ production. Both differential and total cross sections are presented, and we also discuss the possibilities of using accelerator and cosmic antineutrinos to study ${\overline{\nu }}_{e}e$ annihilations.
