标题： Rigorous theory of nuclear fusion rates in a plasma

摘要： 实时热场论被用来揭示等离子体修正对核反应的结构影响。 以前的结果以一种阐明其本质的方式得以恢复，并进行了新的扩展。 布朗和亚夫引入了有效量子场论的方法到等离子体物理学中。 这些方法在这里被用于处理稀疏但电荷非常高的粒子在稀疏单组分等离子体中反应的有趣极限情况。 这些高电荷粒子与背景等离子体有很强的耦合作用。 有效场论证明了平均场解加上一环项占主导地位；即使问题涉及强耦合，高阶环修正也可以忽略不计。 对于非常强的耦合，这样的解析结果很少见，它们可以作为测试计算机模型的基准。 显示英文摘要

摘要： Real-time thermal field theory is used to reveal the structure of plasma corrections to nuclear reactions. Previous results are recovered in a fashion that clarifies their nature, and new extensions are made. Brown and Yaffe have introduced the methods of effective quantum field theory into plasma physics. They are used here to treat the interesting limiting case of dilute but very highly charged particles reacting in a dilute, one-component plasma. The highly charged particles are very strongly coupled to this background plasma. The effective field theory proves that this mean field solution plus the one-loop term dominate; higher loop corrections are negligible even though the problem involves strong coupling. Such analytic results for very strong coupling are rarely available, and they can serve as benchmarks for testing computer models.
