Description
We search for the decay $B_s \to \eta^\prime K_s$ using $121.4 {\rm
~fb^{-1}}$ of data collected at the $\Upsilon(5S)$ resonance with the
Belle detector at the KEKB asymmetric-energy electron-positron collider.
This decay is suppressed in the Standard Model of particle physics and
proceeds through $b \to u$ and penguin transitions, which are sensitive
to new physics. The expected branching fraction in the Standard Model is
approximately $2 \times 10^{-6}$. This decay has not been observed yet.
We use Monte Carlo simulation to study Belle sensitivity to these
decays. We report the current status of our investigations to provide
the best sensitivity to discovering this decay in the existing data.
