Available in PDF, EPUB and Kindle. Book excerpt: The authors present preliminary measurements of the Cp asymmetry parameters and CP content in B{sup 0} {yields} K{sup +}K{sup -}K{sub L}{sup 0} decays, with B{sup 0} {yields} {phi}K{sub L}{sup 0} events excluded. In a sample of 227 M B{bar B} pairs collected by the BABAR detector at the PEP-II B Factory at SLAC, they find the CP parameters to be S = 0.07 {+-} 0.28(stat){sub -0.12}{sup +0.11}(syst); C = 0.54 {+-} 0.22(stat){sub -0.09}{sup +0.08}(syst) where the first error is statistical and the second is systematic. Estimating the fraction of CP-odd final states from angular moments analysis in the K{sup +}K{sup -}K{sub S}{sup 0} CP-conjugate final state, f{sub odd}(K{sup +}K{sup -}K{sub L}{sup 0}) = 0.92 {+-} 0.07(stat) {+-} 0.06(syst), they determine sin2{beta}{sub eff} = 0.09 {+-} 0.33(stat){sub -0.14}{sup +0.13}(syst) {+-} 0.10(syst CP-cont) where the last error is due to uncertainty on the CP content.
