A significant challenge encountered by ground-based gamma-ray observatories is the substantial quantity of cosmic-ray particles that trigger detections. Therefore, it is crucial to implement techniques that can distinguish and separate gamma-ray showers from cosmic-ray showers. The Southern Wide-field Gamma-ray Observatory (SWGO) will be an array of water Cherenkov detectors, currently planned for construction in Chile in the Southern Hemisphere. The current simulation of the observatory includes a set of parameters as potential observables, some of which have demonstrated strong potential for effective Gamma/Hadron separation. In this work, we present an analysis of the performance of the most promising of these observables under different ranges of reconstructed energy, core position, and arrival direction.
