论文摘要
在这篇评论中，我概述了该问题中涉及的概念问题，如何解释所谓的“直接夸克质量测量”，该问题基于大型强子碰撞器（LHC）顶级夸克产品的运动学重建。这些测量值引用了蒙特卡洛事件发生器的最高质量参数$ m_t^{\ rm mc} $，当前不确定性约为$ 0.5 $ GEV。目前，在现场理论中定义的$ M_T^{\ rm MC} $与顶级质量重归化方案之间找到严格的关系的问题尚未解决，并且触及扰动以及非信用方面以及最新的Monte-Carlo事件生成器的限制。我回顾了LHC顶级质量测量的状态，说明了概念限制如何进入和解释在解释问题的背景下渗透社区的争议。总结了获取第一原则洞察力的最新进展，并概述了还必须理解的是充分解决问题。目前，我在做出依赖最高质量的理论预测时给出了一个建议。
In this review I give an overview on the conceptual issues involved in the question how to interpret so-called `direct top quark mass measurements', which are based on the kinematic reconstruction of top quark decay products at the Large Hadron Collider (LHC). These measurements quote the top mass parameter $m_t^{\rm MC}$ of Monte-Carlo event generators with current uncertainties of around $0.5$ GeV. At present time the problem of finding a rigorous relation between $m_t^{\rm MC}$ and top mass renormalization schemes defined in field theory is unresolved and touches perturbative as well as nonperturbative aspects and the limitations of state-of-the-art Monte-Carlo event generators. I review the status of LHC top mass measurements, illustrate how conceptual limitations enter and explain a controversy that has permeated the community in the context of the interpretation problem. Recent advances in acquiring first principle insights are summarized, and it is outlined what else has to be understood to fully resolve the issue. For the time being, I give a recommendation how to deal with the interpretation problem when making top mass dependent theoretical predictions.
