Translation of time-reversal violation in the neutral K-meson system into a table-top mechanical system
Weak interactions break time-reversal (T) symmetry in the two-state system of neutral K-mesons. We present and discuss a two-state mechanical system, i.e. a Foucault-type pendulum on a rotating table, for a full representation of ##IMG## [http://ej.iop.org/images/0954-3899/39/8/083002/jpg427497ieqn1...

| Zusammenfassung: | Weak interactions break time-reversal (T) symmetry in the two-state system of neutral K-mesons. We present and discuss a two-state mechanical system, i.e. a Foucault-type pendulum on a rotating table, for a full representation of ##IMG## [http://ej.iop.org/images/0954-3899/39/8/083002/jpg427497ieqn1.gif] $\rm K^0øverline\rm K^0$ transitions by the pendulum motions including T violation. The pendulum moves with two different oscillation frequencies and two different magnetic dampings. Its equation of motion is identical to the differential equation for the real part of the CPT-symmetric K-meson wavefunction. The pendulum is able to represent microscopic CP and T violation with CPT symmetry owing to the macroscopic Coriolis force, which breaks the symmetry under reversal-of-motion. Video clips of the pendulum motions are given as supplementary material. |
