论文摘要
在开发KRKNLO方案的同时，制定了针对KRK FS的分解方案（FS）作为KRK FS的缩写，其中包括针对初始HADRON的PDF的新定义，该方案与Parton Shower Pashion重型玻色子在HADRON-HADRON碰撞中匹配QCD NLO校正方案，以实现黑德龙碰撞和深度弹性的Lepton Lepton Hadron散射。 KRK FS（最初称为Monte Carlo FS）可以被视为$ \ Overline {MS} $ System的变体。因此，它在整个过程上是独立的。其普遍性的问题是不同的：作为KRK FS的基本作用是简化NLO的校正，现在问题是在KRK FS中PDF的{\ em单}变体是否能够实现{\ em All Processions and All All All Pirtion或Tus Dibter Hadrons and dister Hadrons and no and and and and and and and and and and and and and and and的，则可以实现相同的最大简化nlo校正？我们的答案是积极的，在Catani-Seymour减法方法中的本注释中阐述了证据。 KRK FS是匹配NLO计算和Parton淋浴的KRKNLO方法的强制性 - POWHEG和/或MC \@ nlo的一种简单替代方法。但是，使用KRK FS和相应的PDF可以简化任何其他计算NLO校正和任意过程的方法的NLO计算。
The factorisation scheme (FS) abbreviated as KRK FS including a new definition of the PDFs for initial hadrons was formulated while developing KrkNLO scheme of matching QCD NLO corrections for the hard process with the parton shower heavy boson production in hadron-hadron collision and for deep inelastic lepton-hadron scattering. KRK FS (originally called Monte Carlo FS) can be regarded as a variant of the $\overline{MS}$ system. It is therefore trivially universal, that is process independent. The question of its universality is formulated differently: As the basic role of KRK FS is to simplify drastically NLO corrections, the question is now whether the same {\em single} variant of PDFs in the KRK FS is able to achieve the same maximal simplification of the NLO corrections for {\em all processes} with one or two initial hadrons and any number of the final hadrons? Our answer is positive and the proof is elaborated in the present note within the Catani-Seymour subtraction methodology. KRK FS is mandatory in the KrkNLO method of matching NLO calculation and parton shower -- a much simpler alternative of POWHEG and/or MC\@ NLO. However, the use of KRK FS and the corresponding PDFs simplifies NLO calculations for any other method of calculating NLO corrections and for arbitrary processes as well.
