ççÍ¡Chapter 5Results and Conclusions5.1 MisIDThe measurement of the percentage of pions that were misidentified as muonswas carried out using a large sample K†« ofevents. Results from this study are presented in Figure 5.1 <strong>for</strong> which the following muonidentification cuts were applied:ƒ “ ˆ “ Šdecays using Type-9 K†« dataInner Muon CL¦£.MISSPL¥ .We can see that <strong>for</strong> low momentum the probability of pion misidentification is greaterthan <strong>for</strong> high momentum <strong>for</strong> real data as well as <strong>for</strong> Monte Carlo simulated data.
