修订了$Δm_D$和$ΔΓ_D$
$Δm_D$ and $ΔΓ_D$ revisted
摘要：
用$y_D=(0.80\pm 0.13)%$和$x_D=(0.59 \pm 0.20)%$分别测量了中性$D$介子的寿命差（$y_D=ΔΓ_D/2Γ_D$）和质量差（$x_D=Δm_D/Γ_D$）。有趣的是，与$K$和$B_q$系统的情况相比，目前的数据表明，$y_D/x_D \sim 1$和$y_D$倾向于大于$x_D$。为了解释这一实验现象，我们在非粒子物理的框架下研究了$D-\bar D$振荡。我们证明了{ \it，离壳层非粒子传播子中出现的特殊相位}在$x_D$和$y_D$中起重要作用.
英文摘要：
The lifetime difference ($y_D=ΔΓ_D/2Γ_D$) and mass difference ($x_D=Δm_D/Γ_D$) of neutral $D$ meson have been measured with $y_D=(0.80\pm 0.13)%$ and $x_D=(0.59 \pm 0.20)%$, respectively. Intriguingly, in contrast with the cases of $K$ and $B_q$ systems, the current data indicate that $y_D/x_D \sim 1$ and $y_D$ favors to be larger than $x_D$. For explaining the experimental indication, we here study the $D-\bar D$ oscillation in the framework of unparticle physics. We demonstrate that {\it the peculiar phase appearing in off-shell unparticle propagator} could play an important role on $x_D$ and $y_D$.
