摘要：

We present a measurement of the unitarity triangle angle phi(3) using a Dalitz plot analysis of the three-body decay of the neutral D meson from the B+/--->(DK+/-)-K-(*) process. The method employs the interference between D-0 and (D) over bar (0) to extract both the weak and strong phases. We apply this method to a 140 fb(-1) data sample collected by the Belle experiment. The analysis uses the modes B+/--->DK+/- and B+/--->(DK+/-)-K-*, D-*-->Dpi(0), where the neutral D meson decays into K(S)pi(+)pi(-). We obtain 146 signal candidates for B+/--->DK+/- and 39 candidates for B+/--->(DK+/-)-K-*. From a combined maximum likelihood fit to the B+/--->DK+/- and B+/--->(DK+/-)-K-* modes, we obtain phi(3)=77(-19degrees)(+degrees17)degrees (stat)+/-13degrees(syst)+/-11degrees(model). The corresponding 2 standard deviation interval is 26degrees<phi(3)<126degrees.
