论文摘要
下一代电子 - 戴隆设施有可能显着提高我们对异国黑龙的理解。到目前为止，在光子诱导的反应中尚未看到XYZ状态。他们在这样的过程中的观察将为他们的存在提供独立的确认，并为其内部结构提供新的见解。基于已知的实验数据以及良好的Quarkonium and Regge现象学，我们对几个XYZ状态的独家横截面进行了估计。对于接近阈值的能量，我们预计ZC（3900）+及以上X（3872）的数十个纳米骨的横截面（3900）（3872）都很好，它们在新设施的范围内。
The next generation of electron-hadron facilities has the potential for significantly improving our understanding of exotic hadrons. The XYZ states have not been seen in photon-induced reactions so far. Their observation in such processes would provide an independent confirmation of their existence and offer new insights into their internal structure. Based on the known experimental data and the well-established quarkonium and Regge phenomenology, we give estimates for the exclusive cross sections of several XYZ states. For energies near threshold we expect cross sections of few nanobarns for the Zc(3900)+ and upwards of tens of nanobarn for the X(3872), which are well within reach of new facilities.
