顶夸克是迄今为止观测到的最重的基本粒子。它的巨大质量使得顶夸克成为一个理想的实验室，以测试关于强子对撞机产生重夸克的微扰理论的预测。顶夸克也是对粒子物理学标准模型（SM）之外新现象的有力探索。此外，顶夸克质量是在电弱精密测试中仔细检查SM和预测尚未观测到的希格斯玻色子质量的关键参数。在费米实验室Tevatron发现顶夸克十年后，顶夸克物理学已经进入了一个对顶夸克性质进行详细测量的时代。本文介绍了强子碰撞中顶夸克产生的现象学，总结了Tevatron运行I的经验教训，并讨论了运行II的第一个结果。简要展望了在欧洲核子研究中心正在建设的大型强子对撞机上进行顶夸克研究的可能性。
The top quark is the heaviest elementary particle observed to date. Its large mass makes the top quark an ideal laboratory to test predictions of perturbation theory concerning heavy quark production at hadron colliders. The top quark is also a powerful probe for new phenomena beyond the Standard Model (SM) of particle physics. In addition, the top quark mass is a crucial parameter for scrutinizing the SM in electroweak precision tests and for predicting the mass of the yet unobserved Higgs boson. Ten years after the discovery of the top quark at the Fermilab Tevatron, top quark physics has entered an era where detailed measurements of top quark properties are undertaken. In this paper an introduction to the phenomenology of top quark production in hadron collisions is given, the lessons learned in Tevatron Run I are summarized and the first Run II results are discussed. A brief outlook of the possibilities of top quark research at the Large Hadron Collider, currently under construction at CERN, is included.
