Search for a light CP-odd Higgs boson and low-mass dark matter at the Belle experiment

Belle Collaboration, I. S. Seong, S. E. Vahsen +187

We report on the first Belle search for a light CP-odd Higgs boson, $A^{0}$ , that decays into low mass dark matter, $χ$ , in final states with a single photon and missing energy. We…
