Stability of bound states in the light-front Yukawa model
arXiv:hep-th/0102068 · doi:10.1103/PhysRevD.64.027701
Abstract
We show that in the system of two fermions interacting by scalar exchange, the solutions for J$^Ï$=$0^+$ bound states are stable without any cutoff regularization for coupling constant below some critical value.
