Available in PDF, EPUB and Kindle. Book excerpt: The authors analyze the decay B° 2!KK−K° using 383 million B{bar B} events collected by the BABAR detector at SLAC to extract CP violation parameter values over the Dalitz plot. Combining all KK−K° events, they find A{sub CP} = -0.015 ± 0.077 ± 0.053 and [beta]{sub eff} = 0.352 ± 0.076 ± 0.026 rad, corresponding to a CP violation significance of 4.8[sigma]. A second solution near [pi]/2 - [beta]{sub eff} is disfavored with a significance of 4.5[sigma]. They also report A{sub CP} and [beta]{sub eff} separately for decays to [phi](1020)K°, f0(980)K°, and K+K−K° with m{sub K{sup +}K−}> 1.1 GeV/c2.
