Can new heavy gauge bosons be observed in ultra-high energy cosmic neutrino events?
A wide range of models beyond the Standard Model predict charged and neutral resonances, generically called ${W}^{\ensuremath{'}}$ and ${Z}^{\ensuremath{'}}$ bosons, respectively. In this paper we study the impact of such resonances on the deep inelastic scattering of ultra-high energy neutrinos as well as on the resonant charged current ${\overline{\ensuremath{\nu}}}_{e}{e}^{\ensuremath{-}}$ scattering …
