Measurement of the Resonant and Non-Resonant Branching Ratios in $Ξ_{c}^{0} \to Ξ^{0} K^{+} K^{-}$

J. T. McNeil, J. Yelton, J. Bennett +192

Using the entire data sample of $980$ $f b^{- 1}$ integrated luminosity collected with the Belle detector at the KEKB asymmetric-energy $e^{+} e^{-}$ collider, we present an amplitude…

Search for the dark photon in $B^{0} \to A^{'} A^{'}$ , $A^{'} \to e^{+} e^{-}$ , $μ^{+} μ^{-}$ , and $π^{+} π^{-}$ decays at Belle

S. -H. Park, Y. -J. Kwon, I. Adachi +216

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…
