Measurement of the Absolute Branching Fractions of \(B^+ \rightarrow D^{(*,**)0}\rho ^+\) Reconstruction with the Missing Mass Method
摘要
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 non-strange charm mesons falling in the 2.2–2.8 GeV/c mass range. We present the study of B to charm decays in the Belle experiment with 711 ab \(^{-1}\) simulated samples. For this analysis, we employ the missing mass method, in which the other B-meson is reconstructed in several hadronic final states, and the charm-meson is searched in the recoil of accompanying ( \(\rho \) or \(\pi \) ) mesons.
