OSTI ID:892961
The authors present measurements of the time-dependent CP-violation parameters S and C in B{sup 0} {yields} K{sup 0} decays. The data sample corresponds to 384 million B{bar B} pairs produced by e{sup +}e{sup -} annihilation at the {Upsilon}(4S). The results are S = 0.58 {+-} 0.10 {+-} 0.03, and C = -0.16 {+-} 0.07 {+-} 0.03. They observe mixing-induced CP violation with a significance of 5.5 standard deviations in this b {yields} s penguin dominated mode.
