Track Finding Efficiency in BaBar

We describe several studies to measure the charged track reconstruction efficiency and asymmetry of the BaBar detector. The first two studies measure the tracking efficiency of a charged particle using $τ$ and initial state radiation decays. The third uses the $τ$ decays to study the asymmetry in tracking, the fourth measures the tracking efficiency for low momentum tracks, and the last measures the reconstruction efficiency of $K_S^0$ particles. The first section also examines the stability of the measurements vs BaBar running periods.

Recent CP Violation Studies with BABAR

In this proceeding, results of searches for CP violation in charm decays using the full BABAR dataset are discussed. The parameter $A_{CP}$ in the decay $D^\pm\to\KSπ^\pm$ is determined to be $(-0.39 \pm 0.13 \pm 0.10)%$. Meaurements of CP violation using \T-odd correlations in the four-body decays D^+->K^+K_S^0π^+π^- and D^+_s->K^+K_S^0π^+π^- are $(-12.0 \pm 10.0_{\stat} \pm 4.6_{\syst}) \times 10^{-3}$ and $(-13.6 \pm 7.7_{\stat} \pm 3.4_{\syst}) \times10^{-3}$, respectively.
