通过$pd\rightarrow(^{3}\hspace{-0.03cm}\mbox{He}$-PDMATHAAD（$^{3}\hspace{-0.03cm}\mbox{He} 2γ(6γ$）反应的$η$ -mesic $^{3}\hspace{-0.03cm}\mbox{He}$的非介子衰变
Non-mesonic decay of the $η$-mesic $^{3}\hspace{-0.03cm}\mbox{He}$ via $pd\rightarrow(^{3}\hspace{-0.03cm}\mbox{He}$-$η)_{bound}\rightarrow$ $^{3}\hspace{-0.03cm}\mbox{He} 2γ(6γ$) reaction
摘要：
本文提出了一个$η$ -介$^{3}\hspace{-0.03cm}\mbox{He}$非介子衰变通道的理论模型。我们提出了由此产生的相对动量分布的约束$^{3}\hspace{-0.03cm}\mbox{He}$ - $η$以及在介质中的分支比的$η\rightarrow 2γ$和$η\rightarrow 3π^0$，这是至关重要的蒙特卡罗模拟的测量过程，从而为实验数据的解释。作为一个例子，我们也适用于估计的WASA-at-COSY检测器的检测效率的模型。
英文摘要：
In this article a theoretical model for the $η$-mesic $^{3}\hspace{-0.03cm}\mbox{He}$ non-mesonic decay channels is presented. We present the resultant relative momentum distribution of bound $^{3}\hspace{-0.03cm}\mbox{He}$-$η$ as well as in-medium branching ratios of $η\rightarrow 2γ$ and $η\rightarrow 3π^0$, which are crucial for the Monte Carlo simulations of measured processes and thus for the experimental data interpretation. As an example we also apply the model for the estimation of the detection efficiency of the WASA-at-COSY detector.
