Search for Dark Particles and Dark Sector at Belle
August 02, 2019
We search for dark photon $A^\prime$ and the dark Higgs boson $h^\prime$ particles that are suggested in number of recently proposed dark sector models. We present our search results in the production of $e^+e^- \rightarrow A^\prime h^\prime$ with the decay mod of $h^\prime \rightarrow A^\prime A^\prime$. The search was carried out in both inclusive and exclusive modes. We also discuss a search for new dark vector gauge boson that couples to light quark predominantly.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating
very compact bibliographies which can be beneficial to authors and
readers, and in "proceeding" format
which is more detailed and complete.
