这项工作的目的是详细地描述POWHEG方法，该方法由作者之一首次提出，用于介接部分子簇射发生器和NLO QCD计算。我们描述了该方法的全部一般性，然后在两个用于NLO计算的减法框架中说明了它的特点：Catani-Seymour方法和Frixione-kunszt-Siger方法。在这两种方法中都详细讨论了两个例子：在e(+)e(-)碰撞中产生强子，以及在强子碰撞中产生Drell-yan矢量玻色子。
The aim of this work is to describe in detail the POWHEG method, first suggested by one of the authors, for interfacing parton-shower generators with NLO QCD computations. We describe the method in its full generality, and then specify its features in two subtraction frameworks for NLO calculations: the Catani-Seymour and the Frixione-Kunszt-Signer approach. Two examples are discussed in detail in both approaches: the production of hadrons in e(+)e(-) collisions, and the Drell-Yan vector-boson production in hadronic collisions.
