Book excerpt: Using 385 fb−1 of ee− collisions, they study the amplitudes of the singly Cabibbo-suppressed decay D° → K−K+?°. They measure the strong phase difference between the {bar D}° and D° decays to K*(892)+K− to be -35.5{sup o} ± 1.9{sup o}(stat) ± 2.2{sup o}(syst), and their amplitude ratio to be 0.599 ± 0.013(stat) ± 0.011(syst). They observe contributions from the K? and K−K+ scalar and vector amplitudes, and analyze their angular moments. They find no evidence for charged?, nor for higher spin states. They also perform a partial wave analysis of the K−K+ system in a limited mass range.
