We report the results of a study of charged B decays to the D ±π ±π ± and D* ±π ±π ± final states using complete D(*) reconstruction. The contributions of two-body B→D**π decays with narrow (j = 3/2) and broad (j = 1/2) D** states have been determined and the masses and widths of four D** states have been measured. This is the first observation of the broad P-wave D* 0 0 and D′ 1 0 mesons. The analysis is based on a data sample of 65 million BB̄ pairs collected in the Belle experiment. © 2004 The American Physical Society.
