Abstract

We report on a study of $B$ mesons decaying into one of the narrow P-wave charm resonances, $D_2^{*}(2460)^{0}$ and $D_1(2420)^0$. Our preliminary results are based on 89 million \BB pairs collected with the \babar detector at the PEP-II asymmetric $B$ Factory. Our study will be useful in the investigation of the properties of Heavy Quark Effective Theory.
