This study aims to search for the decay of a B_S meson decaying to neutral K_S and π mesons using 121.4 fb^-1 of data collected by the Belle collaboration using an asymmetric electron-positron collider experiment at the centre of mass energy near the Υ(5S) resonance state. From certain theoretical estimations, the branching fraction of this decay is of the order 10^-8, thus making this event highly unlikely to be found within this dataset. Thus, this study will try to fix an upper bound for this branching fraction limit.
