As we have seen in Sect. 2.4.2, the SM contribution to meson mixing arises at the 1-loop level and is both CKM and GIM suppressed. This makes these observables highly sensitive to new physics contributions (an issue which we will explore further in Chap. 7), and so a precise knowledge of the theoretical predictions is very important.
