  "abstract": "The intrinsic difficulties in extracting the hadron resonances from reaction data are illustrated by using several exactly soluble $\\pi\\pi$ scattering models. The finite-volume Hamiltonian method is applied to predict spectra using two meson-exchange Hamiltonians of $\\pi N$ reactions. Within a three-channel model with $\\pi N$, $\\pi\\Delta$ and $\\sigma N$ channels, we show the advantage of the finite-volume Hamiltonian method over the approach using the L\\\"uscher formula to test Lattice QCD calculations aimed at predicting nucleon resonances. We discuss the necessary steps for using the ANL-Osaka eight-channel Hamiltonian to predict the spectra for testing the LQCD calculations for determining the excited nucleon states up to invariant mass $W= 2 $ GeV.",
