Recent developements in D mixing physics and charm spectroscopy will be
discussed. Focus will be given to the BaBar experimental results for the D
mixing: first evidence of the D0-mixing (hadronic D0 decays), semi-leptonic D0
decays, lifetime difference and time-dependent Dalitz plot analysis of
D0->K+??-??0. Then, recent results on charm spectroscopy will be presented with
particular focus on the many new D, Ds states that have been discovered in the
last few years. Some of these states were not expected theoretically: their
masses, widths, quantum numbers, and decay modes do not ???t the existing
spectroscopic classi???cation, which was based mostly on potential model
calculations.
