Abstract

We analyze the decay B0→K+K-K0 using 383×106 BB̄ events collected by the BABAR detector at SLAC to extract CP violation parameter values over the Dalitz plot. Combining all K+K-K0 events, we find ACP=-0.015±0. 077±0.053 and βeff=0.352±0.076±0.026rad, corresponding to a CP violation significance of 4.8σ. A second solution near π/2-βeff is disfavored with a significance of 4.5σ. We also report ACP and βeff separately for decays to (1020)K0, f0(980)K0, and K+K-K0 with mK+K->1.1GeV/c2. © 2007 The American Physical Society.
