Abstract: Searches for the direct production of low-mass new particles are a priority for the early running period of Belle II. Several topics are candidates for early publications based on the 0.5 fb-1 of data collected during the Spring 2018 commissioning run, or the data to be collected in the ongoing commissioning with the full Belle II detector. These topics include searches for invisible decays of a dark photon, axion-like particles decaying to two photons, or invisible decays of a Z'.
