Measurements of D0-D0bar Mixing and Searches for CP Violation: HFAG Combination of all Data

We present world average values for D0-D0bar mixing parameters x and y, CP violation parameters |q/p| and Arg(q/p), and strong phase differences \delta and \delta_{K\pi\pi}. These values are calculated by the Heavy Flavor Averaging Group (HFAG) by performing a global fit to relevant experimental measurements. The results for x and y differ significantly from zero and are inconsistent with no mixing at the level of 6.7 sigma. The results for |q/p| and Arg(q/p) are consistent with no CP violation. The strong phase difference \delta is less than 45 degrees at 95% C.L.Comment: 8 pages, 5 figures, 4 tables, presented at the BES-Belle-CLEO-Babar Joint Workshop on Charm Physics, November 26-27, 2007 in Beijing China.
