Standard Model fit

The CKM matrix

\[V_{CKM}= \begin{pmatrix} (0.97435 \pm 0.00014) & (0.22501 \pm 0.00064) & (-)e^{i(-65.5 \pm 1.3)^\circ}\\ ( -0.22492 \pm 0.00064)e^{i(0.0362 \pm 0.0011)^\circ} & (0.97345 \pm 0.00014)e^{i(-0.001933 \pm 0.000055)^\circ} & (-) \\ (0.00872 \pm 0.00013)e^{i(-22.53 \pm 0.60)^\circ} & ( -0.04178 \pm 0.00055)e^{i(1.058 \pm 0.028)^\circ} & (0.999088 \pm 0.000024) \end{pmatrix} \]

Fit results

Predictions are obtained by removing the given constraint from the global fit.
