The elementary particles of relativistic quantum field theory are not simple field quanta, as has long been assumed. Rather, they supplement quantum fields, on which they depend on but to which they are not reducible, as shown here with particles defined instead as a unified collection of properties that appear in both physical symmetry group representations and field propagators. This notion of particle provides consistency between the practice of particle physics and its basis in quantum field theory.
相对论量子场论的基本粒子并非如长期以来所认为的那样是简单的场量子。相反，它们对量子场起到补充作用，虽然它们依赖于量子场，但不能简化为量子场，正如这里所展示的，粒子被定义为同时出现在物理对称群表示和场传播子中的一组统一的属性。这种粒子概念在粒子物理学实践及其量子场论基础之间提供了一致性。
