【 摘 要 】

Based on a data sample of an integrated luminosity of 57.4 fb(sup -1) at the (Upsilon)(4S) resonance taken with the BABAR detector using the SLAC PEP-II asymmetric-energy B-Factory, hadronic decays of B meson with the final states D(*) and three pions are studied. The study is performed by fully reconstructing the exclusive decays of B (yields) D(*) a(sub 1)(1260) and the non-resonant modes B (yields) D(*) (rho)(sup 0)(pi) and B (yields) D(*) (pi)(pi)(pi). The current status of the study is presented and a dominant B (yields) D(*) a(sub 1)(1260) decay is shown.
