Abstract
The method of simulation based inference is shown to lead to a more accurate resonance parameter estimation than traditional minimization in certain cases of model misspecification in a case-study of scattering and the -resonance. Models fit to certain datasets using minimization can make inaccurate predictions for the pole position of the . Simulation based inference (SBI) is shown to make a more robust predictions for the pole positions. This is significant, both as a proof of concept that the SBI method can be used in cases of model misspecification, and because models of scattering are a crucial part to many physical systems of contemporary interest [, etc.].
