Abstract

We present a measurement of the unitarity triangle angle φ3 using a Dalitz plot analysis of the three-body decay of the neutral D meson from the B± → D(*)K± process. The method employs the interference between D0 and D̄0 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± → D*K±, D* → Dπ0, where the neutral D meson decays into KSπ + π-. We obtain 146 signal candidates for B ± → DK± and 39 candidates for B ± → D*K±. From a combined maximum likelihood fit to the B± → DK± and B± → D*K± modes, we obtain φ3 = 77° -19°+17° (stat) ± 13°(syst) ± 11°(model). The corresponding 2 standard deviation interval is 26° < φ3 < 126°.

N2 - We present a measurement of the unitarity triangle angle φ3 using a Dalitz plot analysis of the three-body decay of the neutral D meson from the B± → D(*)K± process. The method employs the interference between D0 and D̄0 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± → D*K±, D* → Dπ0, where the neutral D meson decays into KSπ + π-. We obtain 146 signal candidates for B ± → DK± and 39 candidates for B ± → D*K±. From a combined maximum likelihood fit to the B± → DK± and B± → D*K± modes, we obtain φ3 = 77° -19°+17° (stat) ± 13°(syst) ± 11°(model). The corresponding 2 standard deviation interval is 26° < φ3 < 126°.
