We report measurements of time-dependent decay rates for B0 → D*∓π± decays and extraction of C P violation parameters related to φ3. We use a partial reconstruction technique, whereby signal events are identified using information only from the primary pion and the charged pion from the decay of the D*∓. The analysis uses 140 fb-1 of data accumulated at the γ (4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. We measure the C P violation parameters S+ = 0.035 ± 0.041 (stat) ± 0.018 (syst) and S- = 0.025 ± 0.041 (stat) ± 0.018 (syst).

N2 - We report measurements of time-dependent decay rates for B0 → D*∓π± decays and extraction of C P violation parameters related to φ3. We use a partial reconstruction technique, whereby signal events are identified using information only from the primary pion and the charged pion from the decay of the D*∓. The analysis uses 140 fb-1 of data accumulated at the γ (4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. We measure the C P violation parameters S+ = 0.035 ± 0.041 (stat) ± 0.018 (syst) and S- = 0.025 ± 0.041 (stat) ± 0.018 (syst).
