将NLO计算与Parton Shower模拟相匹配:POWHEG方法

Matching NLO QCD computations with Parton Shower simulations: the POWHEG method

Stefano Frixione, Paolo Nason, Carlo Oleari

摘要:

这项工作的目的是详细描述的POWHEG方法,首先建议的作者之一,接口部分子簇射发生器与非线性光学QCD计算。我们描述的方法在其充分的一般性,然后指定其功能在两个减法框架的非线性光学计算:卡塔尼-西摩和Frixione-Kunszt-Signer方法。在这两种方法中详细讨论了两个例子:在e+e-碰撞中强子的产生,以及在强子碰撞中Drell-Yan矢量玻色子的产生。

英文摘要:

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.
