大横动量下改进的Parton簇射

Improved Parton Showers at Large Transverse Momenta

Richard Corke, Torbjörn Sjöstrand

摘要:

通过注入矩阵元信息来改善硬过程的部分子簇射描述的几种方法已经提出了多年。在这篇文章中,我们研究(重)加权方案的第一/最难的排放。一个目标是提供一个一致的匹配的POWHEG下一个领先的顺序发生器的Pythia淋浴算法。另一个是纠正这些阵雨在大的横向动量的默认行为,与实际发射矩阵元素的比较的基础上。

英文摘要:

Several methods to improve the parton-shower description of hard processes by an injection of matrix-element-based information have been presented over the years. In this article we study (re)weighting schemes for the first/hardest emission. One objective is to provide a consistent matching of the POWHEG next-to-leading order generator to the Pythia shower algorithms. Another is to correct the default behaviour of these showers at large transverse momenta, based on a comparison with real-emission matrix elements.
