摘要

我们讨论了排他性的J/psiψ光生成，最初是在NLO的传统对偶因式分解中进行的，然后是在一种包含了低x重和方案和实施关键的低Q_0Q0减法的改进方法中进行的。我们比较和对比了这两种框架的预测结果，并评论了约束和最终确定低x和低尺度胶子PDF的可能性，强调了这对未来全球PDF分析的重要意义。

Implications of exclusive J/$\psi$ photoproduction in a tamed collinear factorisation approach to NLO

We discuss exclusive J/\psiψ photoproduction, initially in conventional collinear factorisation at NLO and then subsequently in a refined approach with a programme of low x resummation and implementation of a crucial low Q_0Q0 subtraction included. We compare and contrast predictions in both frameworks and remark about the possibility to constrain and ultimately determine the low x and low scale gluon PDF, emphasising the significance of this for future global PDF analyses.
