Description:

The neutral K meson, or neutral kaon, K°, and its antiparticle form a remarkable quantum mechanical two-state system that has played an important role in the history of elementary particle physics. Indeed, ever since the discovery of K° half a century ago, neutral kaons have been a rich source of unique and fascinating phenomena associated with their production, decay and propagation in both vacuum and matter. This overview conveys the unique beauty of a quantum-mechanical system that contains so many of the aspects of modern physics.

Neutral Meson Mixing. •Second order weak interactions can mix long-lived neutral mesons with their. • e.g. take the neutral kaons K0 K̅0 as an example neutral kaons free from the detection loophole requires a few % strangeness detection efficiencies. and very high efficiencies for the detection of the kaon decay products. Neutral Kaons. ● The K0 and K0 are eigenstates of the strong interaction. ■ These states have definite strangeness, are not CP eigenstates ■ They are particle/anti-particle. The neutral K meson or neutral kaon, K0, and its antiparticle, K(bar)0, form a remarkable quantum-mechanical two-state system th...
