On-shell renormalization in NREFT: a simplified description of resonances, bound states, and coupled channel effects
Guo-Ying Chen
Abstract
We discuss several issues regarding the modern generalization of Weinberg's compositeness criterion. In particular, we demonstrate that the on-shell renormalization in NREFT reproduces Weinberg's result and provides a simple description of resonances, bound states, and coupled channel effects. Additionally, we present the complete propagator, including the charged channel for the near-threshold p-wave states.
