论文摘要
在这些程序中，我们介绍了有关该过程的研究$γd\ toπ^0ηd$的最新结果，最近最近声称，在$ηd$不变的质量分布中存在二巴里亚人。正如我们将要显示的那样，在实验中观察到的许多相关方面，因为$ηd$和$πd$不变的质量分布相对于相位空间的变化可以用我们的模型来描述，在我们的模型中，没有形成二骨。取而代之的是，我们考虑了$γ$与形成杜特隆的核子的相互作用，以通过$γn\到δ（1700）\至ηδ（1232）\至ηπ^0 n $，然后将$π$和$η$与杜特龙的其他核子进行删除。研究了与Deuteron波函数不同参数有关的理论不确定性
In these proceedings we present our recent results on the study of the process $γd \to π^0 ηd$, where the existence of a dibaryon in the $ηd$ invariant mass distribution has been recently claimed. As we will show, many of the relevant aspects observed in the experiment, as the shift of the $ηd$ and $πd$ invariant mass distributions with respect to phase space can be described with our model, where no dibaryon is formed. Instead, we consider the interaction of the $γ$ with the nucleons forming the deuteron to proceed through $γN \to Δ(1700)\to ηΔ(1232) \to ηπ^0 N$, followed by the rescattering of the $π$ and $η$ with the other nucleon of the deuteron. Theoretical uncertainties related to different parameterizations of the deuteron wave function are investigated
