Abstract
We use νμ-deuteron reactions into exclusive multipion final states to determine the extent to which atmospheric ν interactions can imitate nucleon decay. For decays N→lcπcπc (lcπcπcπ0), neutrinos induce background events at the rate 0.07±0.06 (0.03±0.02) per kiloton year. By requiring a multipion final state to be consistent with a ρ, ω, or η, a fivefold reduction of the background is obtained. Thus presentgeneration experiments are capable of searching for such decays at a lifetime level corresponding to many kiloton years of detector exposure.
