Belle原子$D$介子衰变中的$CP$破坏

$CP$ violation in $D$ meson decays at Belle

K. Prasanth

摘要:

$D$衰变中的$CP$破坏和分支分数测量是有趣的话题,因为与标准模型预测的任何差异都将是新物理的指示。利用位于日本KEKB非对称$e^{+} e^{-}$对撞机相互作用点的Belle探测器收集的大量数据样本,给出了在$D^{0}\rightarrow Vγ~(V = ϕ, \overline{K}^{*0}, ρ^{0})$衰变和罕见的$D$衰变$D^{0}\rightarrow γγ$中寻找$CP$破坏的结果.

英文摘要:

$CP$ violation and branching fraction measurements in $D$ decays are interesting topics as any difference with respect to the Standard Model prediction would be an indication of new physics. With the large data sample collected by the Belle detector, which sits at the interaction point of KEKB asymmetric $e^{+} e^{-}$ collider in Japan, we present the results of searches for $CP$ violation in $D^{0}\rightarrow Vγ~(V = ϕ, \overline{K}^{*0}, ρ^{0})$ decay and the rare $D$ decay $D^{0}\rightarrow γγ$.
