This report summarizes the latest findings from the CAF group on beam halo selections using trigger-based methodologies. A comprehensive analysis was conducted on 1,000 events through minimum bias selections, focusing on the first two detection stations. Key studies explored efficiency metrics with beam halo events, RecHits distributions for minimum bias and cosmic events, and correlation studies between CSC and RPC systems. Insights from various researchers highlight the importance of these findings for improving trigger efficiencies and detector reliability during upcoming experiments.
