G PY 2022 BP 110501 EP 148pp VL 49 IS 11 DI 10.1088/1361-6471/ac89d2 LA English DE tau neutrinos; neutrino experiments; tau neutrino theory AB Tau neutrinos are the least studied particle in the standard model. This whitepaper discusses the current and expected upcoming status of tau neutrino physics with attention to the broad experimental and theoretical landscape spanning long-baseline, beam-dump, collider, and astrophysical experiments. This whitepaper was prepared as a part of the NuTau2021 Workshop. ER
