AI总结：

本文通过分析D介子、Charmonium和ϕ介子衰变数据，检验X17玻色子的存在，发现耦合参数ε_c和ε_s的值与ATOMKI实验结果存在显著矛盾。

摘要：

近期ATOMKI实验提供了指向X17玻色子存在的证据，在铍-8、氦-4和碳-12的异常核转变中。本文考虑X17玻色子对之前测量的D介子衰变的贡献，包括D_s^{*+}→D_s^+ e^+ e^-、D_s^{*+}→D_s^+ γ、D^{*0}→D^0 e^+ e^-以及D^{*0}→D^0 γ，以及测量的ψ(2S)→η_c e^+ e^-、ψ(2S)→η_c γ、ϕ→ηe^+ e^-以及ϕ→ηγ衰变。利用上述介子衰变的数据，我们通过将耦合参数ε_u和ε_c视为独立而非假设生成普遍性ε_u=ε_c来进行拟合。发现上述拟合使|ε_c|=7.6×10^-3，|ε_s|=2.4×10^-3，以及ε_u的极大值，这与ATOMKI测量确定的|ε_u|存在严重矛盾。利用我们拟合的ε_c范围和ATOMKI测量的ε_d范围，我们预测D^{*+}→D^{+} e^+ e^-衰变率范围。

英文摘要：

The recent ATOMKI experiments provided evidence pointing towards the existence of an X17 boson in the anomalous nuclear transitions of Beryllium-8, Helium-4, and Carbon-12. In this work, we consider X17 boson contributions to the previously measured $D$ meson decays which include $D_s^{*+} \rightarrow D_s^+ e^+ e^-$, $D_s^{*+} \rightarrow D_s^+ γ$, $D^{*0} \rightarrow D^0 e^+ e^-$, and $D^{*0} \rightarrow D^0 γ$, as well as the measured decays of $ψ(2S) \rightarrow η_c e^+ e^-$, $ψ(2S) \rightarrow η_c γ$, $ϕ\rightarrow ηe^+ e^-$, and $ϕ\rightarrow ηγ$. Using the data of the above meson decays, we perform a fitting to the coupling parameters $\varepsilon_u, \varepsilon_c$, and $\varepsilon_s$ by treating the couplings $\varepsilon_u$ and $\varepsilon_c$ as independent from each other rather than assuming the generation universality $\varepsilon_u =\varepsilon_c$. It is found that the above fitting renders $|\varepsilon_c|=7.6\times 10^{-3}$, $|\varepsilon_s|=2.4\times 10^{-3}$ and a huge magnitude for $\varepsilon_u$, which is in serious tension with $\left|\varepsilon_u\right|$ determined from ATOMKI measurements. Using our fitted range for $\varepsilon_c$ and the range for $\varepsilon_d$ from ATOMKI measurements, we predict the range for $D^{*+} \rightarrow D^{+} e^+ e^-$ decay rate.
