Testing CP Conservation at KLOE

Abstract

A proposal for maintaining CP conservation in $K_{L}^{0}$ decays is resumed, by adding a heterodox hypothesis. One recovers a consistent picture with a $2\pi$ $K_{L}^{0}$ decay branching ratio proportional to the vertical $K_{L}^{0}$ displacement. This can be clearly tested at the KLOE experiment, where important vertical $K_{L}^{0}$ displacements occur.
