Description
Belle and Belle II have collected world-leading data samples of tau decays. We will report on recent tests of lepton universality and searches for lepton-flavor violation in these decays. They allow us to probe the Standard Model with high precision. Belle II has an unique reach for a broad class of models that postulate the existence of dark matter particles with MeV--GeV masses. We will present recent world-leading results from Belle II searches for several dark matter candidates, as well as the near-term prospects for other dark-sector searches.
