论文摘要
半包含的过程非常有希望在下一代电子 - 戴隆设施中调查$ XYZ $ HADRON，因为它们通常具有较高的横截面。我们将独家光生效的形式主义扩展到半包含的最终状态。预计从Pion Exchange中预计收费的轴向矢量$ Z $状态的包容性生产横截面。我们隔离了$δ$的共振在小缺失质量时的贡献。与独家反应相比，阈值接近阈值的产量大致增强了两倍。我们使用半包含$ b_1^\ pm $生产的数据对模型进行基准测试。
Semi-inclusive processes are very promising to investigate $XYZ$ hadrons at the next generation of electron-hadron facilities, because they generally boast higher cross sections. We extend our formalism of exclusive photoproduction to semi-inclusive final states. The inclusive production cross sections for charged axial-vector $Z$ states from pion exchange are predicted. We isolate the contribution of $Δ$ resonances at small missing mass. Production near threshold is shown to be enhanced roughly by a factor of two compared to the exclusive reaction. We benchmark the model with data of semi-inclusive $b_1^\pm$ production.
