摘要:

在Snowmass 2013白皮书中,我们回顾了用于研究电弱矢量玻色子对和三重产生以及矢量玻色子散射中的非标准电弱相互作用的有效场论方法。我们提出了一个概述的MadGraph5,VBFNLO和WHIZARD中的第六和第八维运营商的实施,并提供这些更高的维度运营商在这些程序中使用的系数之间的关系,并在异常耦合的方法。我们执行调谐比较多玻色子过程的预测,包括非标准的电弱相互作用与MadGraph5,VBFNLO和WHIZARD。我们讨论了高阶修正在这些预测中的作用,使用VBFNLO和POWHEG BOX实现高阶QCD修正WWjj生产。本白皮书旨在收集LHC非标准电子战物理研究的有用工具,比较它们,并研究相关过程中的主要物理问题。

英文摘要:

In this Snowmass 2013 white paper, we review the effective field theory approach for studies of non-standard electroweak interactions in electroweak vector boson pair and triple production and vector boson scattering. We present an overview of the implementation of dimension six and eight operators in MadGraph5, VBFNLO, and WHIZARD, and provide relations between the coefficients of these higher dimensions operators used in these programs and in the anomalous couplings approach. We perform a tuned comparison of predictions for multi-boson processes including non-standard electroweak interactions with MadGraph5, VBFNLO, and WHIZARD. We discuss the role of higher-order corrections in these predictions using VBFNLO and a POWHEG BOX implementation of higher-order QCD corrections to WWjj production. The purpose of this white paper is to collect useful tools for the study of non-standard EW physics at the LHC, compare them, and study the main physics issues in the relevant processes.
