本文研究了横向极化核子中扭曲- 3三胶子相关函数诱导的pp碰撞中D -介子产生、Drell - Yan轻子对产生和直接光子产生的单自旋不对称性。我们给出了一个相对于QCD耦合的前阶极化截面公式和一个不对称的模型计算，说明了对相关函数形式的敏感性。
We study the single spin asymmetries for the D‐meson production, Drell‐Yan lepton‐pair production and the direct‐photon production in the pp collision induced by the twist‐3 three‐gluon correlation functions in the transversely polarized nucleon. We present a corresponding polarized cross section formula in the leading‐order with respect to the QCD coupling and a model calculation for the asymmetries, illustrating the sensitivity to the form of the correlation functions.
