We present a search for the dark photon $A^{'}$ in the $B^{0} \to A^{'} A^{'}$ decays, where $A^{'}$ subsequently decays to $e^{+} e^{-}$ , $μ^{+} μ^{-}$ , and $π^{+} π^{-}$ . T…

Development of ultra-pure NaI(Tl) detectors for the COSINE-200 experiment

B. J. Park, J. J. Choe, J. S. Choi +17

The annual modulation signal observed by the DAMA experiment is a long-standing question in the community of dark matter direct detection. This necessitates an independent verifica…

First search for the $η_{c 2} (1 D)$ in $B$ decays at Belle

Belle Collaboration, K. Chilikin, I. Adachi +194

The first dedicated search for the $η_{c 2} (1 D)$ is carried out using the decays $B^{+} \to η_{c 2} (1 D) K^{+}$ , $B^{0} \to η_{c 2} (1 D) K_{S}^{0}$ , $B^0 \rightarrow η_{c2}(1D) π^…
