【 摘 要 】

Recent measurements in the charm sector at BABAR are reviewed. The scope of the presentation includes the observation of two new narrow mesons in the D(sub s)(sup +)(pi)(sup 0) and D(sub s)(sup +)(pi)(sup 0)(gamma) final states as well as the measurement of D(sup 0)-(bar D)(sup 0) mixing parameters by means of two methods: using the doubly-Cabibbo-suppressed D(sup 0) decay to K(sup +)(pi)(sup -) and using the ratios of lifetimes extracted from samples of D(sup 0) mesons decaying to K(sup -) (pi)(sup +), K(sup -)K(sup +), and (pi)(sup -)(pi)(sup +).
