摘要：While the HALQCD method has become popular for obtaining hadron interactions from lattice QCD simulations, it has been often criticized for its unclear systemic uncertainties, especially the derivative expansion method to determine the potential from the Nambu-Bethe-Salpeter (NBS) wave functions. In this talk, I will use an example to demonstrate that general potentials cannot be accurately fixed by a small number of NBS wave functions. Additionally, we propose using the Ernst-Shakin-Thaler (EST) method to extract the hadron-hadron interaction from NBS wave functions. I will showcase its effectiveness using a realistic nucleon force, which is more efficient than the derivative expansion in handling very nonlocal interactions and also provides a way to estimate the systemic uncertainties of the derivative expansion.
