The D0 experiment operated at the Fermi National Accelerator Laboratory (FNAL) proton-antiproton Tevatron collider from 1992 until 2011, and has produced nearly 500 scientific publications to date. Notable among the results during that period was the discovery of the top quark in 1995. During this period, the Tevatron was the world's highest energy collider. This position now goes to the Large Hadron Collider (LHC) at CERN (proton-proton), but the Tevatron still has some advantages because it is a proton- antiproton collider. This makes a large number of proton and antiproton constituent particles, quark-antiquark collisions, as opposed to the LHC collisions that are dominated by intermediary particles called gluons. This enables unique measurements of quark-dominated processes, including some aspects of single top quark production via the Electroweak interaction and asymmetries between forward and backward produced top quarks or hadrons containing bottom quarks.Analysis of the D0 data continues with some 40 additional publications expected over the next two years. These will contain further studies of the top quark, the Higgs boson and the nature of the strong force. This award will fund one of the two spokespersons of the D0 experiment. The spokespersons are responsible for all physics analyses and guiding them toward publication. They provide mentoring for the graduate students and postdocs conducting analyses, and oversee the internal review of analyses by more senior members of the collaboration. In addition, the spokespersons represent the collaboration to the FNAL Directorate, the funding agencies, other experiments, and the general public.About 500 students have been trained within the D0 experiment, and a similar number of postdoctoral fellows have matured as scientists within the collaboration. The training of students and postdocs will continue through the analyses conducted during this grant. As in the past, we expect that these young men and women will enter careers in physics education and research, medical science, information technology, financial firms and government service. The mentoring of these people is one of the most important tasks of the D0 spokespersons, and provides one of the most lasting impacts on society by the experiment.

D0 实验从 1992 年到 2011 年在费米国家加速器实验室 (FNAL) 质子-反质子 Tevatron 对撞机上进行，迄今为止已发表了近 500 篇科学出版物。这一时期取得的成果中值得注意的是 1995 年发现了顶夸克。在此期间，Tevatron 是世界上最高的能量对撞机。这一位置现在由欧洲核子研究中心（质子-质子）的大型强子对撞机（LHC）占据，但 Tevatron 仍然具有一些优势，因为它是质子-反质子对撞机。这会产生大量的质子和反质子组成粒子，即夸克-反夸克碰撞，而不是大型强子对撞机碰撞以称为胶子的中间粒子为主。这使得能够对夸克主导的过程进行独特的测量，包括通过电弱相互作用产生单顶夸克的某些方面，以及向前和向后产生的顶夸克或包含底夸克的强子之间的不对称性。对 D0 数据的分析仍在继续，预计在未来两年内还会有大约 40 篇其他出版物。这些将包含对顶夸克、希格斯玻色子和强力本质的进一步研究。 该奖项将资助 D0 实验的两名发言人之一。发言人负责所有物理分析并指导其发表。他们为研究生和博士后进行分析提供指导，并监督合作中更高级成员对分析的内部审查。此外，发言人还向 FNAL 理事会、资助机构、其他实验和公众代表了此次合作。大约 500 名学生在 D0 实验中接受了培训，类似数量的博士后研究员在合作中已成为成熟的科学家。通过这笔资助期间进行的分析，将继续对学生和博士后进行培训。与过去一样，我们预计这些年轻男女将进入物理教育和研究、医学、信息技术、金融公司和政府服务领域。对这些人的指导是 D0 发言人最重要的任务之一，也是该实验对社会最持久的影响之一。
