英文摘要	We report measurements of time-dependent decay rates for B-0-> D(-/+)pi(+/-) decays and extraction of CP violation parameters related to phi(3). 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 Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. We measure the CP violation parameters S+ = 0.035 +/- 0.041 (stat) +/- 0.018 (syst) and S- = 0.025 +/- 0.041 (stat) +/- 0.018 (syst). (c) 2005 Elsevier B.V. All rights reserved.
