This talk presents recent world-leading physics results from Belle II searches for Z’ decays; as well as the near-term prospects for other dark-sector searches. In addition, we presented a related search for lepton-flavor-violating τ decays to a lepton and an invisible boson. 000003514 8560_ $$fdjaffe@bnl.gov
