Abstract

Since its start, the Large Hadron Collider (LHC) has helped advance both theory and experiment on the production and properties of the heaviest fundamental particle, the top quark. This review focuses on a selected set of measurements and associated searches for new physics, which have opened the door for unprecedented precision in this area of high-energy physics. Fundamental parameters of the theory such as m t , α S , V tb , and y t are measured from top quark events with relative uncertainties that are smaller than 0.5%, 1.8%, 2%, and 10%, respectively, and that are expected to improve with more data, better experimental methods, and more accurate theory predictions. Several results, even if statistically limited, already significantly constrain the phase space of new physics: measurements of associated production with bosons, processes with four top quarks, and searches for rare decays, among others. It is expected that until the completion of the LHC program, top quark physics will keep providing unique insights regarding the consistency of the Standard Model and the energy scale of new physics.

大型强子对撞机顶夸克的物理学:对未来道路的评价和展望

从一开始，大型强子对撞机(LHC)就帮助推进了最重的基本粒子顶夸克的产生和性质的理论和实验。这篇综述的重点是一组选定的测量和与新物理相关的搜索，这些测量和搜索为高能物理领域前所未有的精确度打开了大门。理论的基本参数，如m t， α S, V tb和y t，是由顶夸克事件测量的，相对不确定度分别小于0.5%，1.8%，2%和10%，并且随着更多的数据，更好的实验方法和更准确的理论预测，有望得到改善。有几个结果，即使在统计上有限，已经显著地限制了新物理学的相空间:测量与玻色子相关的生产，四个顶夸克的过程，以及寻找罕见的衰变，等等。预计在大型强子对撞机项目完成之前，顶夸克物理学将继续为标准模型的一致性和新物理的能量尺度提供独特的见解。

期刊介绍： The Annual Review of Nuclear and Particle Science is a publication that has been available since 1952. It focuses on various aspects of nuclear and particle science, including both theoretical and experimental developments. The journal covers topics such as nuclear structure, heavy ion interactions, oscillations observed in solar and atmospheric neutrinos, the physics of heavy quarks, the impact of particle and nuclear physics on astroparticle physics, and recent advancements in accelerator design and instrumentation. One significant recent change in the journal is the conversion of its current volume from gated to open access. This conversion was made possible through Annual Reviews' Subscribe to Open program. As a result, all articles published in the current volume are now freely available to the public under a CC BY license. This change allows for greater accessibility and dissemination of research in the field of nuclear and particle science.
