Book excerpt: We report on an improved measurement of the Cabibbo-Kobayashi-Maskawa CP-violating phase? through a Dalitz plot analysis of neutral D meson decays to K{sub s}°??− and K{sub s}°K+K− produced in the processes B{sup {-+}} → DK{sup {-+}}, B{sup {-+}} → D* K{sup {-+}} with D* → D?°, D?, and B{sup {-+}} → DK*{sup {-+}} with K8{sup {-+}} → K{sub S}°?{sup {-+}}. Using a sample of 383 million B{bar B} pairs collected by the BABAR detector, we measure? = (76 ± 22 ± 5± 5){sup o} (mod 180{sup o}), where the first error is statistical, the second is the experimental systematic uncertainty and the third reflects the uncertainty on the description of the Dalitz plot distributions. The corresponding two standard deviation region is 29{sup o}
