We observe an excess of signal events with a significance of 5.2 standard deviations including systematic uncertainties and measure the branching fraction to be B(B-0 -> (KSK +/-)-K-0 pi(-/+) (sic) (3.2 +/- 0.5 +/- 0.3) x 10(-6), where the uncertainties are statistical and systematic, respectively. %R 10.1103/PhysRevD.82.031101 %U http://arXiv.org/abs/1003.0640 %U https://doi.org/10.1103/PhysRevD.82.031101 %P 031101-8pp
