抽象。 在纳尔逊的无质量模型的单粒子部分, 在相互作用中,对于任意小的红外截止, 系统的哈密顿量。所执行的方法是一种建设性的 一个只利用正规扰动理论,通过一个合适的迭代方案。 在没有红外正则化的情况下,单粒子态消失。 还探讨了一些参数的规律性等建设性特征。
Abstract. In the one-particle sector of Nelson’s massless model, the one-particle states are constructed for an arbitrarily small infrared cutoff in the interaction term of the Hamiltonian of the system. The performed method is a constructive one which exploits only regular perturbation theory, by a suitable iteration scheme. The disappearance of one-particle states is showed in the limit of no infrared regularization. Constructive features, as regularity in some parameters, are also inquired.
