Abstract
We present the angular analysis of $B\rightarrow J/\psi K^*$, $B\rightarrow \psi(2S) K^*$ and $B\rightarrow \chi_{c1} K^*$, using $112 fb^{-1}$ data of the BaBar detector at the PEP-II $e^+e^-$ machine. This angular analysis aims at measuring the decay transversity amplitudes in absolute value and strong phases. This allows to probe the hadronic form factor models of Factorization scheme in color-supressed modes. This study represent an update with increased luminosity for $B\rightarrow J/\psi K^*$ decays, the first BaBar measurement in $B\rightarrow \psi(2S) K^*$ decays, and the first measurement ever in $B\rightarrow \chi_{c1} K^*$ decays.
