Description
Most of the hadronic B decays observed proceed through a "D" meson (D, D$^*$, D$^{**}$) , as b$\rightarrow $c transitions dominate among other b transitions. D$^{**}$ indicates the collection of non-strange charm mesons falling in the mass range of 2.2 - 2.8 GeV/c$^2$.
We present the study of B to charm decays in the Belle experiment with 711 fb$^{-1}$ electron-positron collision data recorded at the center of mass energy at the $\Upsilon$(4S) resonance mass. For this analysis, we employ the missing mass method, in which the other B-meson is reconstructed in several hadronic final states, and charm-meson is searched in the recoil of accompanying ($\rho$ or $\pi$) mesons. The study will result in the first measurement of the decay B$\rightarrow $D$^{**}\rho$.
