Ultra-high energy neutrinos and $W^{\prime }$, $Z^{\prime }$ gauge bosons at the Pierre Auger Observatory

Abstract

A wide range of models beyond the Standard Model predict charged and neutral resonances, generically called $W^{\prime }$- and $Z^{\prime }$-bosons, respectively. We present a study of the impact of such resonances on the deep inelastic scattering of ultra-high energy neutrinos as well as on the resonant charged current ${\bar{\nu }}_e{e}^{-}$ scattering (Glashow resonance). We find that the effects of such resonances can not be observed with the Pierre Auger Observatory or any foreseeable upgrade of it.
