Description
Based on the full data set recorded with the BABAR detector at center-of-mass energies at and near the Upsilon(4S) resonance, and corresponding to an integrated luminosity of approximately 468 fb-1, we measure the D0-D0bar mixing parameters using a time-dependent amplitude analysis of the decay D0 -> pi+pi-pi0.
With the same BABAR data set, we also measure the mass difference, Delta m, between the D*(2010)+ and the D+ using the decay chain D*(2010)+ -> D+ pi0 with D+ -> K- pi+ pi+. We additionally combine this result with a previous BABAR measurement of m(D*(2010)+) - m(D0) and obtain results that are approximately seven times more precise than the present world averages.
