Abstract
Presented are preliminary results from the BABAR Collaboration on charm physics, including limits on D 0 mixing from the ratio of lifetimes from K − π +, K + K −, and π + π − final states (using 47.8 fb −1 of data) and branching ratio, and Dalitz amplitude analyses of the decays D 0 → K 0K −π +, K 0 K +π − , and K 0 K +K − (using 22 fb −1 of data). The status of direct measurements of D 0 mixing using wrong-sign D 0 → K + π − decays is also discussed.
