Abstract

The decays of neutral kaons produced in phiv decay, phivrarrK L K S , exhibit interesting quantum mechanical interference. The effects of this phenomenon on searches for CP violation have been previously been worked out for two body decays where the decay amplitude is a simple constant. For three body modes where the matrix element varies across the kinematically allowed region, the quantum correlations with enhance or cancel certain terms in the decay distribution. We work out the results for two interesting modes phivrarr(pgrpgr)(pgrpgrgamma) and phivrarr(3pgr)(3pgr). In the former case, the quantum correlation allows the isolation of the direct emission component of the pgrpgrgamma decay, while in the latter case the intensity asymmetry can uniquely pick out the direct CP violating amplitude.
