Abstract

We report the results of the first search for the decay $B_{s}^{0} \to η^{'} K_{S}^{0}$ using $121.4 {fb}^{- 1}$ of data collected at the $ϒ (5 S)$ resonance with the Belle detector at the KEKB asymmetric-energy $e^{+} e^{-}$ collider. We observe no signal and set a 90% confidence-level upper limit of $8.16 \times 10^{- 6}$ on the $B_{s}^{0} \to η^{'} K_{S}^{0}$ branching fraction.
