Measurements of D0-D0bar Mixing and Searches for CP Violation: HFAG Combination of all Data
arXiv:0803.0082 · doi:10.1088/1674-1137/32/6/014
Abstract
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 δand δ_{Kππ}. 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 δis less than 45 degrees at 95% C.L.
