Cosmic ray signatures of multi-W processes

Abstract We explore the discovery potential of cosmic ray physics experiments for Standard Model processes involving the nonperturbative production of ⪆ 〈FO3〉(α w −1 ) ⋍ 30 weak gauge bosons. We demonstrate an experimental insensitivity to proton-induced processes and emphasize the importance of neutrino-induced processes. The Fly's Eye currently constrains the largest region of parameter space characterizing multi-W phenomena if a cosmic neutrino flux exists at levels suggested by recent models of active galactic nuclei. MACRO (DUMAND) can constrain or observe additional regions by searching for 1–100 (1–10) characteristic near-vertical (near-horizontal) spatially compact energetic muon bundles per year.
