Abstract: We analyze the decay B0 -> K+ K- K0 using 383 million B-Bbar eventscollected by the BaBar detector at SLAC to extract CP violation parametervalues over the Dalitz plot. Combining all K+ K- K0 events, we find A CP =-0.015 +- 0.077 +- 0.053 and beta eff = 0.352 +- 0.076 +- 0.026 rad,corresponding to a CP violation significance of 4.8 sigma. A second solutionnear pi-2 - beta eff is disfavored with a significance of 4.5 sigma. We alsoreport A CP and beta eff separately for decays to phi1020 K0, f0980 K0, andK+ K- K0 with m {K+ K-} > 1.1 GeV-c^2.
