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{sup 0} {yields} K{sub S}{sup 0}{pi}{sup 0} decays with 227 million {Upsilon}(4S) {yields} B{bar B} events collected with the BABAR detector at the PEP-II asymmetric-energy e{sup +}e{sup -} collider at SLAC. They obtain a branching fraction {Beta}(B{sup 0} {yields} K{sup 0}{pi}{sup 0}) = (11.4 {+-} 0.9 {+-} 0.6) x 10{sup -6} and CP-violating asymmetry parameters C{sub K{sub S}{sup 0}{pi}{sup 0}} = 0.06 {+-} 0.18 {+-} 0.03 and S{sub K{sub S}{sup 0}{pi}{sup 0}} = 0.35{sub -0.33}{sup +0.30} {+-} 0.04, where the first error is statistical and the second systematic.
