Abstract: We report on the first Belle search for a light CP-odd Higgs boson, A0, that decays into low mass dark matter, ?, in final states with a single photon and missing energy. We search for events produced via the dipion transition (2S)? (1S)?+?-, followed by the on-shell process (1S)??A0 with A0???, or by the off-shell process (1S)????. Utilizing a data sample of 157.3�106 (2S) decays, we find no evidence for a signal. We set limits on the branching fractions of such processes in the mass ranges MA0<8.97 GeV/c2 and M?<4.44 GeV/c2. We then use the limits on the off-shell process to set competitive limits on WIMP-nucleon scattering in the WIMP mass range below 5 GeV/c2. � 2019 authors. Published by the American Physical Society.
