... Discussion 2.2 Considering the case k = 2 (two di↵erent amplitudes), can you show that |Āf¯/Af | = 1 if either 1 = 2 or 1 = 2 ? This type of CP violation can also occur in neutral meson decays. The contributions can be difficult to disentangle. As it involves strong phases that a hard to calculate, ...

Electroweak precision data and right-handed gauge bosons
... The most stringent available limits on MWR then, arise from the KL − KS mass diference. As a matter of fact, under the following assumptions: (a) the left-right symmetry is manifest or pseudomanifest (b) the hadronic matrix elements are computed in the vacuum saturation approximation. Beall, Bander ...
