At the right side we see the caparisonbetween the mass ¤¡¤£ ¦difference from simulated and real data reconstructed¤¡ ¨§¡from and normalized to one.The efficiencies were calculated using the Monte Carlo simulation.In our case wegenerated 2362319 events of¡¤£©¡ § ¡and 2223732 events of¡¤£©¡ § ©.The efficiencies calculation was simply as the Appendix C equation (C.4) presents. Themass plots of the simulated data used to determine the number of reconstucted events arethe figure 5.8 (right side), and the figure 5.9 (right side). The reconstructed events from thereal data were determined from mass plots in the figure 5.6 (right side), and the figure 5.7(right side). Having all the needed information we calculated our branching ratio (equation(5.13)).£¡ ¢¢ £¡¥ ¥ (5.13)¢¡¡ ¡ ¤
