关于合并矩阵元与Parton簇的注记

Tutorial Note on Merging Matrix Elements with Parton Showers

Thomas Rössler

摘要:

在这个简短的说明中,我介绍了矩阵元素合并算法的基本概念特征和主要构建块,在前导阶和次前导阶的固定阶计算上操作。其目的纯粹是教学,即以简明的方式使读者熟悉基本的基本概念,从而为初学者和其他感兴趣的读者提供介绍。简单讨论了单一化。本教程高度偏向于横向动量有序部分子簇射,特别是合并方案,因为它们是在Pythia8通用蒙特卡罗生成器中实现的。

英文摘要:

In this short note, I introduce to essential conceptual features and main building blocks of matrix element merging algorithms, operating on fixed order calculations both at leading order and next-to-leading order. The intention is purely pedagogical, i.e. to familiarize the reader with the essential basic concepts in a concise way, thus serving as an introduction to beginners and other interested readers. Unitarization is discussed briefly. The tutorial is highly biased towards transverse momentum ordered parton showers, and in particular towards merging schemes as they are implemented in the Pythia8 general purpose Monte Carlo generator.
