Measurement of ϕ3 with Dalitz Plot Analysis of B+→D(∗)K(∗)+ Decay

Results from the Belle and BaBar experiments on measurement of the weak angle ϕ3 using a Dalitz plot analysis of the decay of the neutral D meson from the B±→D(∗)K(∗)± process are presented. The method employs the interference between D0 and to extract the angle ϕ3, strong phase δ and the ratio r of suppressed and allowed amplitudes.
