我们建议寻找错误的位移顶点，其中次级顶点的衰变产物移向主顶点，而不是远离它，作为微观违反因果关系的签名。我们详细分析了最近提出的Lee-Wick标准模型的轻子部分，它提供了一个很好的动机框架来研究因果效应。我们发现，假设最小味违反，电子的李-威克伙伴，e和，可以在LHC产生可测量的错误顶点，最有希望的通道是qe+e−jjjj。使用MadGraph/MadEvent的蒙特-卡罗模拟表明，对于Ml 450 GeV，这些非因果顶点位移的测量在LHC时代应该是可访问的。
We propose to search for wrong displaced vertices, where decay products of the secondary vertex move towards the primary vertex instead of away from it, as a signature for microscopic violation of causality. We analyze in detail the leptonic sector of the recently proposed Lee-Wick Standard Model, which provides a well motivated framework to study acausal effects. We find that, assuming Minimal Flavor Violation, the Lee-Wick partners of the electron, e and , can produce measurable wrong vertices at the LHC, the most promising channel being qe+e−jjjj. A Monte-Carlo simulation using MadGraph/MadEvent suggests that for Ml450 GeV the measurement of these acausal vertex displacements should be accessible in the LHC era.
