NLO中的轻子碰撞

Lepton collisions in MadGraph5_aMC@NLO

Stefano Frixione, Olivier Mattelaer, Marco Zaro, Xiaoran Zhao

摘要:

MadGraph5_aMC@NLO是一个软件包,它允许人们模拟任意复杂的过程,在领先和次领先阶微扰精度,有或没有匹配和多喷流合并到部分子簇射。它是为强子碰撞而设计的,到目前为止主要用于强子碰撞。在这篇文章中,我们记录了一些技术特性的实现,这些技术特性是将其范围扩展到现实的ee对撞机环境所必需的。我们只限于讨论非偏振光束的情况下,但我们指出,偏振光束的治疗是概念上相同的,我们建立的结构可以很容易地扩展到进行模拟μ子对撞机。

英文摘要:

MadGraph5_aMC@NLO is a software package that allows one to simulate processes of arbitrary complexity, at both the leading and the next-to-leading order perturbative accuracy, with or without matching and multi-jet merging to parton showers. It has been designed for, and so far primarily employed in the context of, hadronic collisions. In this note, we document the implementation of a few technical features that are necessary to extend its scope to realistic ee collider environments. We limit ourselves to discussing the unpolarized beam case, but we point out that the treatment of polarized beams is conceptually identical, and that the structure we set up can easily be extended to carry out simulations at muon colliders.
