Abstract

We present results from BABAR experiment for the measurement of inclusive and exclusive branching fractions of B mesons into final states containing $J/\psi$, $\psi(2S)$ and $\chi_c$. The contributions of CP even and odd amplitudes in the decay $B^0 \to J/\psi K^{*0}$ are determined from an angular analysis. We report the measurements of the branching ratios $B^0 \to D^{*+}D^{*-}$ and $D^{*+}D^{*-}K^0_S$, and the study of exclusive two-body and quasi-two-body charmless decays. The branching fraction of the decay $B^0 \to K^{*0} \gamma$ has been determined and the corresponding CP asymmetry has been measured.
