论文摘要
我们研究了重新分解组方程（RGE）的扰动溶液中的滞后作用。我们介绍了QCD运行耦合和质子的Parton分布功能（PDF），该函数与大型强子对撞机（LHC）和未来对撞机实验的精度物理学有关。我们建议使用重新召集量表来考虑RES解决方案的理论不确定性。作为案例研究，我们考虑了与PDF提取有关的区域中$ F_2 $结构的功能。
We investigate hysteresis effects in the perturbative solution of renormalisation group equations (RGEs). We present examples for the QCD running coupling and proton's parton distribution functions (PDFs), relevant to precision physics at the Large Hadron Collider (LHC) and future collider experiments. We propose the use of resummation scales to take into account the theoretical uncertainties from the solution of the RGEs. As a case study, we consider the $F_2$ structure function in a region relevant to the extraction of PDFs.
