论文摘要
理所当然的是，结合的系统是由通过粒子交换相互作用的大量组成的（通过光子交换相互作用的带电颗粒，通过Gluon交换相互作用的夸克，而核中的核子通过中膜交换相互作用）。但是，正如最近发现的那样，存在以交换粒子为主的系统（至少对于零交换质量）。在这些系统中，大量成分的贡献可以忽略不计。这些系统具有相对论的性质（因为它们主要由以光速运动的无质量颗粒制成），因此，施罗丁格方程无法描述它们。尽管到目前为止，这些结果是在简单的Wick-cutkosky模型中发现的（通过无旋转无质量交换的梯子相互作用的无旋构成分），但它们存在的物理基础似乎是相当笼统的。
It is taken for granted that bound systems are made of massive constituents that interact through particle exchanges (charged particles interacting via photon exchanges, quarks in elementary particles interacting via gluon exchanges, and nucleons in nuclei interacting via meson exchanges). However, as was recently theoretically found, there exist systems dominated by exchange particles (at least for the zero exchange masses). In these systems, the contribution of massive constituents is negligible. These systems have a relativistic nature (since they are mainly made of massless particles moving at the speed of light), and therefore, they cannot be described by the Schroedinger equation. Though these results were found so far in the simple Wick--Cutkosky model (spinless constituents interacting via the ladder of spinless massless exchanges), the physical ground for their existence seems to be rather general.
