Antihydrogen and Antiproton Studies

反氢原子是一个正电子和一个反质子的结合态，是完全由反物质构成的最简单的原子。这个不寻常的原子是在磁场中产生并悬浮的，磁场使反物质原子悬浮在一个中心位置。精确比较反氢原子和它们对应的物质的性质的智力价值来自于检验最基本物理理论的预测的可能性，即物质和反物质粒子是“完全相反的”，具有相反的符号和相同的质量的电荷，反物质原子和物质原子具有完全相同的性质。有充分的理由相信，最基本的物理理论并不是一个完整的描述。因此，发现反物质和物质原子结构之间的差异将导致基础物理学理论的改进，其结果对科学和未来技术具有潜在的重要意义。此外，这项研究是一些最有天赋的理科生和博士后的训练基地，为他们在科技领域的成功职业生涯做好准备，这是一个科技社会蓬勃发展所需要的。为这类基础研究开发的方法通常会得到更普遍的应用。最后，许多关于这门科学的讲座被用来教育学生、专业科学家和公众。

The antihydrogen atom, a bound state of a positron and an antiproton, is the simplest atom made entirely of antimatter. This unusual atom has been produced and suspended within magnetic fields that keep the antimatter atoms suspended at a central location. The intellectual merit of precise comparisons of the properties of the antihydrogen atoms and their matter counterpart arises from the possibility of testing the prediction of the most fundamental physics theory, namely that matter and antimatter particles are "exactly opposite", with charges of opposite sign and masses that are identical, and that antimatter atoms and matter atoms have precisely the same properties. There are good reasons to believe that the most fundamental physics theory is not a complete description. Discovering a difference between the structure of antimatter and matter atoms would thus lead to an improved theory of fundamental physics, the consequences of which are potentially important for science and future technology. Moreover, this research is the training ground for some of the most gifted science students and postdocs, preparing them for the successful careers in science and technology that are needed for a technological society to thrive. Methods developed for such fundamental research typically find their way into more common applications. Finally, many lectures on this science are used to educate students, professional scientists, and the general public.
