Blessed Figures

The following figures have been blessed for the $B$ lifetime measurements analysis. More detailed informations can be found in CDF note 7386.

Figure 1: Efficiency distribution Comparison. For $B^{+} \to J/\psi K^{+}$ decay mode is possible to extract the efficiency distribution directly from data. This plot shows the comparison between the efficiency distributions coming from Data ( black ) and Realistic Monte Carlo ( red ). A $\chi ^{2}$ test over the two distributions gives a probability of 52%.

Figure 2: Wide Mass Region Fits: A Mass fit on a wide mass region is performed before to run the combined fit, in order to fix the mass shape of the combinatorial background and estimate the contamination coming from partially reconstructed background. These fits show the projection results for the $B^{0}$ decay modes.

Figure 3: Wide Mass Region Fits: A Mass fit on a wide mass region is performed before to run the combined fit, in order to fix the mass shape of the combinatorial background and estimate the contamination coming from partially reconstructed background. These fits show the projection results for the $B_{s}$ decay modes.

Figure 4: Projection plots for the combined Mass-Lifetime fit on $B^{0}\to D^{-}\pi ^{+}$ decay mode. $B_{s}$ and $\Lambda _{b}$ contributions are taken into account with ad hoc Monte Carlo templates. The partially reconstructed contribution is less then 1% and then can be neglected.

Figure 5: Projection plots for the combined Mass-Lifetime fit on $B^{0}\to D^{-}\pi ^{+}\pi ^{-}\pi ^{+}$ decay mode. The partially reconstructed contribution is less then 1% and then can be neglected.
