Title: Measurement of CP Asymmetry in B{sup 0} --> K{sup +}K{sup -}K{sup 0}S Decays

Abstract

The authors present preliminary measurements of the CP asymmetry parameters and CP content in B{sup 0} --> K{sup +}K{sup -}K{sub s}{sup 0} decays, with {phi}K{sub s}{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 = -0.42 {+-} 0.17 {+-} 0.04 and C = 0.10 {+-} 0.14 {+-} 0.06, where the first error is statistical and the second systematic. Extracting the fraction of CP-even final states from angular moments f{sub even} = 0.89 {+-} 0.08 {+-} 0.06, and setting C = 0, they determine sin 2{beta} = 0.55 {+-} 0.22 {+-} 0.04 {+-} 0.11, where the last error is due to uncertainty on the CP content.
