Measurement of phi3 with Dalitz Plot Analysis of B+- -> D K*+- Decay
K. Abe
Abstract
We present a measurement of the unitarity triangle angle phi3 using a Dalitz plot analysis of the three-body decay of the neutral D meson from the B+- -> D K*+- process. Using a 253 fb-1 data sample collected by the Belle experiment, we obtain 56 signal candidates for B+- -> D K*+-, where the neutral D meson decays into KS pi+ pi-. From a maximum likelihood fit we obtain phi3=112+-35(stat)+-9(syst)+-11(model)+-8(nonresonant B -> D KS pi).
