40 Chapter 5. Probing <strong>the</strong> Standard Model<br />
The results <strong>of</strong> <strong>the</strong> Standard Global CKM Fit for <strong>the</strong> Wolfenstein parameters A, λ, ¯ρ,<br />
¯η and <strong>the</strong> Jarlskog invariant J are shown in Figure 5.4. Fur<strong>the</strong>rmore, <strong>the</strong> fit results<br />
<strong>of</strong> <strong>the</strong> UT angles α, β and γ are compared with <strong>the</strong>ir SM predictions and <strong>the</strong>ir<br />
direct measurements. In this case, SM prediction means <strong>the</strong> result <strong>of</strong> <strong>the</strong> Standard<br />
Global CKM Fit without <strong>the</strong> respective parameter in <strong>the</strong> fit. The numerical results<br />
<strong>of</strong> <strong>the</strong> relevant observables and model parameters are summarized in Table 5.3 & 5.4.<br />
