Abstract

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).
