摘要

$K^{+}\to\pi^{+}\pi^{0}\pi^{0}\gamma$衰减由OKA协作观察到。分支比率测量为$\left(3.3\pm 0.8(\textrm{stat.})\right)\times 10^{-6}$。分支比和$\gamma$能谱与ChPT预测结果一致。

Search for the $\boldsymbol{K^{+}\rightarrow}{\pi^{+}\pi^{0}\pi^{0}\gamma}$ Decay

The $K^{+}\to\pi^{+}\pi^{0}\pi^{0}\gamma$ decay is observed by the OKA collaboration. The branching ratio is measured to be $\left(3.3\pm 0.8(\textrm{stat.})\right)\times 10^{-6}$. The branching ratio and $\gamma$ energy spectrum are consistent with ChPT prediction.
