Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, F. Abudinén, I. Adachi, L. Aggarwal, H. Aihara | Summary: The dark photon $A^prime$ and the dark Higgs boson $h^prime$ are hypothetical particles predicted in many dark sector models. We search for the simultaneous production of $A^prime$ and $h^prime$ in the dark Higgsstrahlung process […]
