论文摘要
我们计算出生产轴向矢量$ f_1（1285）$介中的横截面，用于$ e^+ e^ - \ to e^+ e^ - f_1（1285）$反应的双重测量。使用了不同的$γ^*γ^* \ to f_1（1285）$来自文献的顶点。计算了集成的横截面以及差分分布。提出了Belle II潜在测量的预测。文献中提出的不同顶点获得了完全不同的结果。以$ E^+ E^ - $ colliders的未来测量值可以测试和/或将$γ^*γ^* \限制为F_1（A_1，F_1'）$顶点和相关的形式，已知是计算Muon和Muon spline spline spline spline spline Muimant spemant sompts of muimistications atm sompational placting的重要成分。
We calculate cross sections for production of axial-vector $f_1(1285)$ mesons for double-tagged measurements of the $e^+ e^- \to e^+ e^- f_1(1285)$ reaction. Different $γ^* γ^* \to f_1(1285)$ vertices from the literature are used. Both integrated cross section as well as differential distributions are calculated. Predictions for a potential measurement at Belle II are presented. Quite different results are obtained for the different vertices proposed in the literature. Future measurements at $e^+ e^-$ colliders could test and/or constrain the $γ^* γ^* \to f_1 (a_1, f_1')$ vertices and associated form factors, known to be important ingredients for calculating contributions to anomalous magnetic moment of muon and hyperfine splitting of levels of muonic atoms.
