D0-D0bar Mixing and CP Violation: HFAG Combination of Parameters
arXiv:0911.1464
Abstract
We present the most recent set of world averages for D0-D0bar mixing and CP violation parameters, as obtained by the Heavy Flavor Averaging Group from a global fit to various measurements. The values obtained for the mixing parameters when allowing for CP violation are x= (0.98 +0.24 -0.26)% and y= (0.83 +-0.16)%; the significance of mixing is 10.2 sigma. There is no evidence for CP violation at the current level of sensitivity.
