  Powerful jets and outflows generated in tidal disruption events (TDEs) around
supermassive black holes have been suggested to be possible sites producing
high-energy neutrinos, but it is unclear whether such environment can provide
the bulk of the neutrinos detected by the IceCube Observatory. In this work, by
considering realistic limits on the non-thermal emission power of a TDE jet and
the birth rate of the TDEs with jets pointing towards us, we show that it is
hard to use the jetted TDE population to explain the flux and the isotropic
arrival directions of the observed TeV-PeV neutrinos. Therefore, TDEs cannot be
the dominant sources, unless those without aligned jets can produce wide-angle
emission of neutrino particles. Supposing that is the case, we list a few
recent jetted and non-jetted TDEs that have the best chance to be detected by
IceCube, based on their energetics, distances, and directions. A spatial and
temporal association of these predicted events with the IceCube data should
provide a decisive test on the full TDE population as origins of the IceCube
neutrinos.
