摘要
We present world average values for D^0-D^0 mixing parameters x and y, CP violation parameters |q/P| and Arg(q/p), and strong phase differences δ and δKππ. 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 6.7a. The results for |q/P| and Arg(q/p) are consistent with no CP violation. The strong phase difference δ is less than 45° at 95% C.L.
