| contents | Baryon number violation is our most sensitive probe of physics beyond the Standard Model, especially through the study of nucleon decays. Angular momentum conservation requires a lepton in the final state of such decays, kinematically restricted to electrons, muons, or neutrinos. We show that operators involving taus, which are at first sight too heavy to play a role in nucleon decays, still lead to clean nucleon decay channels with tau neutrinos. While many of them are already constrained from existing two-body searches such as $p\to π^+ν$, other operators induce many-body decays such as $p \to ηπ^{+} \barν_τ$ and $n\to K^+ π^-ν_τ$ that have never been searched for. |
