论文摘要
我们研究了半含量的非弹性散射中产生的横向极化，$ ep \ toeλ^\ uparrow x $，在共线扭曲3分解的框架内。相对于QCD耦合常数，根据twist-3分布函数的横截面和Twist-3夸克碎片函数是在领先顺序上计算的。考虑到Twist-3 FF之间的约束关系以简化公式。该公式与未来电子离子挑战器实验中的大$ P_T $ Hyperon生产有关。
We study the transverse polarization of hyperons produced in semi-inclusive deep inelastic scattering, $ep\to eΛ^\uparrow X$, in the framework of the collinear twist-3 factorization. The cross section from the twist-3 distribution functions and the twist-3 quark fragmentation functions is computed in the leading order with respect to the QCD coupling constant. The constraint relations among the twist-3 FFs are taken into account to simplify the formula. The formula is relevant to large-$P_T$ hyperon production in the future Electron-Ion-Collider experiment.
