The CP-even fraction of D0 & RARR; K0S & pi;+& pi;- & pi;0 decays is determined to be 0.235 & PLUSMN; 0.010 & PLUSMN; 0.002, where the first uncertainty is statistical and the second is systematic.eninfo:eu-repo/semantics/openAccessSearchPhaseArticle1083WOS:0010639864000022-s2.0-85169326979N/A10.1103/PhysRevD.108.032003Q1
