Abstract

We report the results of a study of charged B decays to the ${D}^{\ifmmode\pm\else\textpm\fi{}}{\ensuremath{\pi}}^{\ensuremath{\mp}}{\ensuremath{\pi}}^{\ensuremath{\mp}}$ and ${D}^{*\ifmmode\pm\else\textpm\fi{}}{\ensuremath{\pi}}^{\ensuremath{\mp}}{\ensuremath{\pi}}^{\ensuremath{\mp}}$ final states using complete ${D}^{(*)}$ reconstruction. The contributions of two-body $\stackrel{\ensuremath{\rightarrow}}{B}{D}^{**}\ensuremath{\pi}$ 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 $D{\ensuremath{'}}_{1}^{0}$ mesons. The analysis is based on a data sample of 65 million $B\overline{B}$ pairs collected in the Belle experiment.
