论文摘要
基本光量量化（BLFQ）是一种新开发的非扰动方法，旨在基于轻度动力学的哈密顿形式主义解决相对论结合系统。在这项工作中，我们将其应用于强耦合的正电子系统，$α= 0.3 $，动态光子介导了正电子和电子之间的相互作用。需要非扰动的质量重归其化以取消费米昂的自我能力差异。在这里，我们介绍所得的质谱，光较前波函数（LFWFS）和正电子中的光子分布。
Basis Light-front Quantization (BLFQ) is a newly developed nonperturbative approach, aiming at solving relativistic bound systems based on the Hamiltonian formalism of light-front dynamics. In this work, we introduce its application to the positronium system at strong coupling, $α= 0.3$, with a dynamical photon mediating the interaction between the positron and the electron. Nonperturbative mass renormalization is needed to cancel the fermion self-energy divergence. Here, we present the resulting mass spectrum, light-front wave functions (LFWFs), and the photon distribution inside positronium.
