The CP LEAR Project: PS195

Abstract

It has been proposed by Adieis et al to carry out tests of CP violation with K⁰ and K̄⁰ at LEAR by measuring interference effects and asymmetries of the different amplitudes in the 2π, 3π and semi-leptonic decay channels. These measurements will be possible when intense p̄ beams are available from late 1987 after construction of the p̄ accumulator (ACOL) at CERN. The symmetrical production of K⁰ and K̄⁰ in p̄p annihilation at rest was shown by Gabathuler and Pavlopoulos to have particular advantages in minimising systematic errors compared to other measurement techniques where K_S and K_L are used in investigating CP violation. Because of this new technique if there is new physics to be seen, the well controlled systematics of this experiment will enable it to be seen at the level of the anticipated statistical and systematic uncertainties.
