Abstract
Recent developements in D mixing physics and charm spectroscopy will be discussed. Focus will be on the BaBar experimental results for the D mixing: first evidence of the D0-mixing (hadronic D0 decays), lifetime difference and time-dependent Dalitz plot analysis of D0→K+π−π0. Then, recent results on charm spectroscopy will be presented with particular focus on the new 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 fit the existing spectroscopic classication, which is based mostly on potential model calculationsI documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
