英文摘要：

I present here the HFAG averages for the parameters that regulate flavor mixing and \CP violation in the neutral $D$ meson system. I also discuss recent results from the $B$ factories for the measurements of the mixing parameter \yCP and the \CP violation parameter \deltaY (\AGamma) in the lifetime ratio analysis of the transitions to the \CP-even eigenstates $\Dz\to K^+K^-,π^+π^-$, relative to the transitions to the \CP-mixed state $\Dz \to K^-π^+$.

D^0-D^0bar mixing in Υ(1S) \to D^0 D^0bar decay at Super-B

$\Dz-\Dzb$ mixing and significant CP violation in the charm system may indicate the signature of new physics. In this study, we suggest that the coherent $\DzDzb$ events from the decay of $Υ(1S) \to \Dz \Dzb$ can be used to measure both mixing parameters and CP violation in charm decays. The neutral $D$ mesons from $Υ(1S)$ decay are strongly boosted, so that it will offer the possibility to measure the proper-time interval, $Δt$, between the fully-reconstructed $\Dz$ and $\Dzb$. Both coherent and time-dependent information can be used to extract $\Dz-\Dzb$ mixing parameters. The sensitivity of…

CP violation and mixing in the charm sector at Belle, and current HFAG averages

Current HFAG averages of the mixing and CP violation parameters in the $D^0$ meson system is to be reviewed. We present recent Belle measurements of the mixing parameters $x$ and $y$ using $D^0\rightarrow K^0_Sπ^+π^-$, and $y_{CP}$ and $A_Γ$ from $D^0\rightarrow h^+h^-$, $D^0\rightarrow K^-π^+$, where $h$ denotes $K$ or $π$. Belle measurements of direct CP violation in $D^+\rightarrow K^0_Sπ^+$, $D^0\rightarrow h^+h^-$, and $D^+\rightarrow K^0_SK^+$ decays together with $ΔA^{hh}_{CP}$ are to be presented.

D0-D0bar Mixing and CP Violation: HFAG Combination of Parameters

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.

Measurements of D0-D0bar Mixing and Searches for CP Violation: HFAG Combination of all Data

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.

Indirect CP violation results and HFAG averages

The current status of the search for indirect CP violation in the neutral D meson system at the B-factories and at LHCb is reported. The indirect CP asymmetry search is performed by the measurement of the proper-time asymmetry ($A_Γ$) in decays of $D^0-\bar{D^0}$ mesons to CP eigenstates, $K^-K^+$ and $π^- π^+$, and by $y_{CP}$, the ratio between the effective lifetime measured in decay to a CP eigenstate and that to the mixed eigenstate $K π$. All results are consistent with the no CP violation hypothesis. The latest world averages for mixing and CP asymmetry in the charm sector evaluated by …

HFAG-charm averages

The extraction of charm mixing and CP violation parameters requires the combination of many measurements. The latest averages are reviewed and the contribution of individual measurements is discussed. While it is established that the CP-even eigenstate is the shorter lived, the oscillation frequency of charm mesons is still not known to high accuracy. All CP asymmetries are found to be compatible with zero within less than 3 sigma.
