摘要：
We present world average values for D-0-(D) over bar (0) mixing parameters x and y, CP violation parameters vertical bar q/p vertical bar 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 vertical bar q/p vertical bar and Arg(q/p) are consistent with no CP violation. The strong phase difference delta is less than 45 degrees at 95% C.L.
