註釋The authors present a preliminary measurement of the branching fraction and CP-violating parameters S and C for the decay B{sup 0} {yields} {omega}K{sub S}{sup 0}. The data sample corresponds to 232 x 10{sup 6} B{bar B} pairs produced from e{sup +}e{sup -} annihilation at the {Upsilon}(4S) resonance. They measure {Beta}(B{sup 0} {yields} {omega}K{sup 0}) = (5.9 {+-} 1.0 {+-} 0.4) x 10{sup -6}, S = 0.50{sub -0.38}{sup +0.34} {+-} 0.02 and C = -0.56{sub -0.27}{sup +0.29} {+-} 0.03.
