    "abstract": "The $^8Be$ anomaly reported by the Atomki experiments can be explained by the hypothesis of an $X(17)$ boson that interacts with electrons via the ``Vector $\\pm$ Axial-vector\u0027\u0027 ($V \\pm A$) interaction. Using existing experimental data, we derive constraints on the couplings of the $X(17)$ boson to electrons within this $V \\pm A$ framework. With this setup, we attempt to identify $X(17)$ signals in the $e^+e^- \\longrightarrow X(17) \\longrightarrow e^+e^-$ process at the PADME experiment and in the $e^+e^- \\longrightarrow X(17)\\gamma \\longrightarrow e^+e^- \\gamma$ process at the BESIII experiment. Our findings indicate that observing the $X(17)$ signal at the PADME experiment is pessimistic, whereas the BESIII experiment may provide a definitive answer regarding the $X(17)$ hypothesis.",
