Measurements of D^0-0 mixing and searches for CP violation:HFAG combination of all data

导出

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.
