论文摘要
我们讨论了独家$ j/ψ$光生效,最初是在NLO的常规共线化分解中,然后在精制的方法中使用低$ x $重新定义的程序进行了精制方法,并实施了关键的低$ q_0 $减法。我们比较了两个框架中的预测和对比预测,并说明了约束和最终确定低$ x $和低规模Gluon PDF的可能性,这强调了这对于未来的全球PDF分析的重要性。
We discuss exclusive $J/ψ$ 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 $Q_0$ 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.
