Abstract
We report the observation of the decay B--> D(pi)(+)pi(-)pi(0)K(-), where D(pi)(+)pi(-)pi(0) indicates a neutral D meson detected in the final state pi(+)pi(-)pi(0), excluding K(S)(0)pi(0). This doubly Cabibbo-suppressed decay chain can be used to measure the CKM phase gamma. Using about 229x10(6) e(+)e(-)-> B (B) over bar events recorded by the BABAR experiment at the PEP-II e(+)e(-) storage ring, we measure the branching fraction B(B--> D(pi)(+)pi(-)pi(0)K(-))=(5.5 +/- 1.0(stat.)+/- 0.7(syst.))x10(-6) and the decay rate asymmetry A(B--> D(pi)(+)pi(-)pi(0)K(-))=-0.02 +/- 0.16(stat.)+/- 0.03(syst.) for the full decay chain.
