论文摘要
通过标量无质量交换相互作用的两个大型标量颗粒的伯特 - 钙板方程具有两种类型的解决方案，它们在非相关性极限中的行为彼此不同：变成库仑的溶液和“异常”溶液。后者没有非权利主义的对应物，并且在非相关性极限中消失。我们研究了所有这些状态的组成。事实证明，即使对于大结合能，正常状态也以两个巨大的颗粒为主。而两体部门对异常状态的贡献，即使对于小结合能，也仅为1％。它们由无限量的无质量颗粒主导。计算了正常状态和异常状态的弹性电磁形式因素，以及它们之间的转变。
The Bethe-Salpeter equation for two massive scalar particles interacting by scalar massless exchange has solutions of two types, which differ from each other by their behavior in the non-relativistic limit: the normal solutions which turn into the Coulomb ones and the "abnormal" solutions. The latter ones have no non-relativistic counterparts and disappear in the non-relativistic limit. We studied the composition of all these states. It turns out that the normal states, even for large binding energy, are dominated by two massive particles. Whereas, the contribution of the two-body sector into the abnormal states, even for small binding energy, is of the order of 1% only; they are dominated by an indefinite number of the massless particles. The elastic electromagnetic form factors for both normal and abnormal states, as well as the transition ones between them, are calculated.
