论文摘要
我们介绍了Feynrules中的DMSIMPT模型实现，该模型旨在提供一个独特的通用框架，允许对围栏和互补宇宙学计算的简化$ t $ channel暗物质模型相关的所有模拟。我们描述了如何与Parton Shaters匹配近代QCD固定顺序计算，以在LHC暗物质搜索的上下文中得出强大的界限和预测，并验证两个模型限制（分别与Dirac和Majoraana Fermionic Dark Matters相关）（与Dirac和Majorana fermionic Dark Matters相关），以评估如何评估暗物质在构造模型的模型参数范围。更重要的是，我们强调如何使用公开可用的自动化工具的组合来实现这些结果，并讨论暗物质预测对模型文件和软件设置的敏感性。所有文件以及说明性Mathematica笔记本电脑都可以从url http://feynrules.irmp.ucl.ac.be/wiki/dmsimpt获得。
We present the DMSimpt model implementation in FeynRules, which aims to offer a unique general framework allowing for all simulations relevant for simplified $t$-channel dark matter models at colliders and for the complementary cosmology calculations. We describe how to match next-to-leading-order QCD fixed-order calculations with parton showers to derive robust bounds and predictions in the context of LHC dark matter searches, and moreover validate two model restrictions (relevant for Dirac and Majorana fermionic dark matter respectively) to exemplify how to evaluate dark matter observables to constrain the model parameter space. More importantly, we emphasise how to achieve these results by using a combination of publicly available automated tools, and discuss how dark matter predictions are sensitive to the model file and software setup. All files, together with illustrative Mathematica notebooks, are available from the URL http://feynrules.irmp.ucl.ac.be/wiki/DMsimpt.
