Description
The authors present preliminary measurements of the CP asymmetry parameters in B0 → KS0KS0KS0 decays, reconstructing two of the KS0 into π+π- and one into π0π0. In a sample of 227 M B(bar B) pairs collected by the BABAR detector at the PEP-II B Factory at SLAC, they find the CP parameters to be S = -0.25-0.61+0.68(stat) ± 0.05(syst) and C = 0.56-0.43+0.34(stat) ± 004(syst). Combining this result with the previous BABAR measurement, obtained from events with three KS0 decaying into π+π-, they get S -0.63-0.28+0.32(stat) ± 0.04(syst); C = -0.10 ± 0.25(stat) ± 0.05, (syst)
