Abstract

We report the results of the first search for the decay Bs0→η′KS0B_s^0 \to η^\prime K_S^0 using 121.4 fb−1121.4\,{\rm fb}^{-1} of data collected at the Υ(5S)Υ(5S) resonance with the Belle detector at the KEKB asymmetric-energy e+e−e^+ e^- collider. We observe no signal and set a 90\% confidence-level upper limit of 8.16×10−68.16 \times 10^{-6} on the Bs0→η′KS0B_s^0 \to η^\prime K_S^0 branching fraction.
