论文摘要
快速插值网格框架有助于对Parton分布功能的任何选择或强耦合$α_s$的任何选择的高阶预测进行有效且灵活的评估。它们构成了提取Parton分布函数和标准模型参数的必不可少的工具，以及对横截面对重量级化和分解量表的依赖性的研究。 Applfast Project提供了Parton级蒙特卡洛发电机NNLOJET与网格插值的Applgrid和FastNlo库之间的通用接口。介绍了该项目的扩展，以在扰动QCD中近代到领先的订单以及在LHC的JET生产申请中，在近代到领先的订单中的扩展。
Fast interpolation-grid frameworks facilitate an efficient and flexible evaluation of higher-order predictions for any choice of parton distribution functions or value of the strong coupling $α_s$. They constitute an essential tool for the extraction of parton distribution functions and Standard Model parameters, as well as studies of the dependence of cross sections on the renormalisation and factorisation scales. The APPLfast project provides a generic interface between the parton-level Monte Carlo generator NNLOJET and both the APPLgrid and the fastNLO libraries for the grid interpolation. The extension of the project to include hadron-hadron collider processes at next-to-next-to-leading order in perturbative QCD is presented, together with an application for jet production at the LHC.
