An ultralarge liquid argon time projection chamber based neutrino detector will have the uncommon ability to detect atmospheric ντ/ ν̄τ events. This paper discusses the most promising modes for identifying charged current ντ̄τ, and shows that, with simple kinematic cuts, ∼30ντ̄τ interactions can be isolated in a 100kt•yr exposure, with greater than 4σ significance. This sample is sufficient to perform flux-averaged total cross-section and cross-section shape parametrization measurements-the first steps toward using ντ̄τ to search for physics beyond the standard model.
