Dark Sector Models
Dr. Igal Jaegle (University of Florida)

The dark photon, A´, the dark Higgs boson, h´, and the dark Baryon, B´, are hypothetical constituents featured in a number of recently proposed Dark Sector Models. Dark Sector particles can be produced in the so-called dark Higgsstrahlung and radiative processes, and in neutral D-meson decays channels. We will present results for the search of dark sector particles with prompt and displaced vertex decay topologies, when applicable, obtained using 1ab -1 of data collected by the Belle detector and we will discuss the discovery potential of the Belle II experiment when 50ab-1 of data will be collected within the next decade.
