$CP$-violating asymmetries in $B^0 \rightarrow a_1(1260)^{\pm} \pi^{\mp}$

We present preliminary measurements of $CP$-violating asymmetries for $B^0 \rightarrow a_1(1260)^{\pm} \pi^{\mp}$ decays and of branching fractions for the $B^0$ decays to $K_1(1270)^+ \pi^-$ and $K_1(1400)^+ \pi^-$. The dataset consists of approximately 384 million $B\bar{B}$ pairs produced in electron-positron annihilation and recorded by the BaBar detector.
