| الوصف: | We present a preliminary measurement of CP-violation parameters in the decay B 0 → K + K − K 0 S, using approximately 465 million BB events collected by the BABAR detector at SLAC. Reconstructing the neutral kaon as K 0 S → π+ π − or K 0 S → π0 π 0, we analyze the Dalitz plot distribution and measure fractions to intermediate states. We extract CP parameters from the asymmetries in amplitudes and phases between B 0 and B 0 decays across the Dalitz plot. From a fit to the whole Dalitz plot, we measure βeff = 0.44 ± 0.07 ± 0.02, ACP = 0.03 ± 0.07 ± 0.02, where the first uncertainties are statistical and the second ones are systematic. For decays to φK 0 S, we measure βeff = 0.13 ± 0.13 ± 0.02, ACP = 0.14 ± 0.19 ± 0.02. For decays to f0K 0 S, we measure βeff = 0.15 ± 0.13 ± 0.03, ACP = 0.01 ± 0.26 ± 0.07.
