Measurement of the Branching Fraction and the CP-Violating Asymmetry for the Decay B0 to K0s Pi0
The authors measure the branching fraction and the CP-violating asymmetry of B° 2!K{sub S}°[pi]° decays with 227 million [Upsilon](4S) 2!B{bar B} events collected with the BABAR detector at the PEP-II asymmetric-energy ee− collider at SLAC. They obtain a branching fraction [Beta](B° 2!K°[pi]°) = (11.4 ± 0.9 ± 0.6) x 10−6 and CP-violating asymmetry parameters C{sub K{sub S}°[pi]°} = 0.06 ± 0.18 ± 0.03 and S{sub K{sub S}°[pi]°} = 0.35{sub -0.33}{sup +0.30} ± 0.04, where the first error is statistical and the second systematic.
