Abstract
We search for the decay Bs → η'η using 121.4 fb−1 of data collected at the Υ(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 transitions sensitive to new physics. The expected branching fraction for Bs → η'η in the Standard Model is 33.5×10−6. This decay has not been observed yet. We use Monte Carlo simulation to optimize our selection criteria for signal events and a Neural Network to separate signal from background. Our study maximizes discovery potential for this process.
