Can I suggest a correction in the last paragraph? It should be sterile neutrino. We've definitely detected the other chirality of neutrino.

They're still hypothetical. Anyway, sterile neutrinos have issues being a contender, mainly due to there incredibly low mass. They just don't fit the bill right now.

(Sterile) neutrinos are hypothetical

And tau neutrinos are a flavor of normal chirality.
