Study of rare and hadronic B decays in BABAR

Abstract

We present results from BABAR experiment for the measurement of inclusive and exclusive branching fractions of B mesons into final states containing $J/\ddot{I}ˆ$, $\ddot{I}ˆ(2S)$ and $\ddot{I}{‡}_c$. The contributions of CP even and odd amplitudes in the decay $B^0\to J/\ddot{I}ˆK^{\ast 0}$ are determined from an angular analysis. We report the measurements of the branching ratios $B^0\to D^{\ast +}{D}^{\ast -}$ and $D^{\ast +}{D}^{\ast -}{K}_S^0$, and the study of exclusive two-body and quasi-two-body charmless decays. The branching fraction of the decay $B^0\to K^{\ast 0}{\hat{I}}^3$ has been determined and the corresponding CP asymmetry has been measured.
