Description
In this talk, we present recent studies of semi-invisible final states of various processes in the Belle and Belle II experiments. In particular, we cover the following results: lepto-philic Z' decays to invisible final states and dark photon search in the dark-Higgsstrahlung process, both in the e+ e- continuum, search for invisible baryon-like dark matter particle in the B-mesogenesis scheme, search for invisible particle in tau decays, and search for heavy neutral lepton in tau decays.
